Materials and Method: This is a retrospective descriptive study covering the period of January 1982 to December 2022, based on the medical records of patients operated on for a primary cardiac tumor at the Abidjan Heart Institute. Results: Twenty-seven (27) patients underwent surgery for a primary cardiac tumor, including 14 women and 13 men with a mean age of 41.5 years (range 19 - 76 years). The main circumstances of discovery were exertional dyspnea, palpitation and syncope or pseudo-syncope. The main site was the septal wall of the left atrium. The diagnosis of myxoma was confirmed by pathological examination of the surgical specimen in 96.3% (n = 24) of the patients and it was a malignant large cell immunoblastic lymphoma of the myocardium in 3.7% (n = 1) of the patients. The mean largest diameter was 46.1 mm. The postoperative course was marked by an ischaemic stroke (n = 1);recurrence of a left atrial myxoma 5 years after the first tumor removal (n = 1). Two cases of death were noted, one due to the evolution of immunoblastic large cell lymphoma and the other due to an extracorporeal circulation accident. Conclusion: Almost all primary cardiac tumors operated on in Abidjan are myxomas. The circumstances of the discovery of these cardiac tumors are multiple and varied but dominated by exertional dyspnea, palpitation and syncope. Whatever their histological type, primary cardiac tumors are serious affections, in view of the haemodynamic and rhythmic disorders they cause.展开更多

We report on a 59-year-old female patient, who was admitted to the hospital due to the discovery of bilateral breast masses for 3 months, there was no paresthesia or dyskinesia. The patient accidentally found a mass in the right upper mediastinum while completing a plain chest X-ray, initially suspected as a benign neurilemmoma on CT. Surgical resection and pathological analysis confirmed an intraneural hemangioma. Unexpectedly, the patient developed new-onset right upper limb numbness and paresthesia 3 months post-operatively, probably related to surgical nerve injury. This case underscores the importance of maintaining a broad differential for mediastinal masses, and the potential for iatrogenic neurological complications when managing these rare, yet vascular lesions.展开更多

Bone involvement is reported ...Hydatid disease is caused by Echinococcus granulosus parasite. It is an endemic disease;particularly in many Mediterranean countries. The liver and the lungs are most frequently involved. Bone involvement is reported in 1% - 2% of the cases and about 50% of those are seen in the spine. Herein we report a case of primary spinal extradural hydatid cyst that caused paraplegia due to compression of the dorsal spinal cord and was diagnosed initially as case of lumber prolapsed intervertebral disc. The cyst was only discovered when the patient had progressive paraplegia and the preoperative provisional diagnosis was posterior mediastinal neurogenic tumor causing destruction of the pedicle and lamina of the fifth thoracic vertebra. Fortunately, she regained near full power after surgical treatment of her spinal cyst.展开更多

We herein report a rare case of CUP of a mediastinal lymph node. A 61-year-old man with dermatomyositis was referred to our hospital for treatment of mediastinal adenopathy and gastric cancer. Biopsy of both lesions showed that they were histologically different from each other. Mediastinal lymphadenectomy and total gastrectomy were performed for a definitive diagnosis and radical cure. Pathological examination revealed two distinctly different disease processes. The patient underwent postoperative chemotherapy for residual gastric cancer. Twenty months postoperatively, he is alive with cancer. Although CUP usually has a poor prognosis, surgical treatment of metastatic mediastinal lymph node CUP is a feasible therapeutic option.展开更多

Many ganglioneuroma cases are detected incidentally unless they are large enough to cause compressive symptoms. We report an 18-year-old patient with posterior mediastinal ganglioneuroma which was abutting the descending aorta. The patient underwent successful resection by thoracoscopic approach and was followed up for one year with no complications. In summary, a detailed review with experts in both radiology and pathology is mandated to diagnose these tumors. Informed consent was obtained from the patient.展开更多
文摘Cystic lesions of the anterior mediastinum in children suggest a well-known group of benign lesions that are comparatively frequent.Thymic cysts(TCs)are mostly positioned in the anterior mediastinum and some patients in the neck.Benign TCs classified as congenital intra-thoracic mesothelial cysts are commonly asymptomatic and have slight clinical significance.Multilocular TC,which can mimic another anterior mediastinal cystic tumor and is seen in adults,is more clinically important.It is a sporadic mediastinal lesion thought to arise in the course of acquired inflammation.Congenital mediastinal cysts represent 3%-6%of all mediastinal tumors and 10%-18%of radiologically reported mediastinal masses.Mediastinal TCs are uncommon and it is hard to know their true incidence.About 60%of cases with mediastinal TCs are asymptomatic,and the remainder of patients complains of nonspecific symptoms(e.g.,chest pain,dyspnea,or cough).The literature suggests that most cysts are benign,but an indefinite percentage may have a neoplastic process and result in significant compressive symptoms over time.Clinical symptoms of TCs vary depending on the location.In addition,frequent symptoms at the appearance of enlarged benign thymic and mediastinal cysts generally contain compressive symptoms(e.g.,respiratory distress,thymic pain,and symptoms related to Horner syndrome,hoarseness,dysphonia,dyspnea,orthopnea,wheezing,and fever).Many TCs have cystic density and a neat border and are simple to diagnose with radiological imaging.However,some TCs are hard to identify before surgery and may be misidentified as thymomas depending on their site and computed tomography results.Excision by thoracotomy,median sternotomy,or video-assisted techniques is essential for conclusive diagnosis,management,and abolition of relapse of anterior mediastinal masses and TCs.Histopathologic examination may be required after surgery.Considering the extent of the mass and the preliminary inability to make a definitive diagnosis,en bloc excision of the cyst was thought to be preferred to circumvent likely complications(e.g.,perforation,spillage of the contents,or incomplete excision).

文摘BACKGROUND Multiple primary malignant tumors(MPMTs)was first described by Billroth as early as 1889,with the first report published by Warren and Gates in 1932.Since then,numerous cases have been reported.A literature review of 1104269 patients with cancer revealed that the incidence of MPMTs ranged from 0.73 to 11.7%.In recent years,however,there has been a significant upward trend in the incidence of this phenomenon,which may be associated with many different factors,including the advancement of modern diagnostic procedures facilitating the examination and diagnosis of more MPMTs,increased exposure to chemotherapy and radiotherapy that exacerbate the risk of new malignant tumors in patients with cancer,and prolonged survival of patients with cancer allowing sufficient time for the development of new primary cancers.AIM To analyze the incidence,clinical features,treatment factors,prevalence,and prognosis of patients with MPMTs in the gastrointestinal tract treated in a single center.Additionally,we analyzed the different tumor combinations,time interval between the occurrence of tumors,and staging.METHODS This retrospective cohort study analyzed 8059 patients with pathologically confirmed gastrointestinal malignant tumors treated at the Gansu Province Hospital in Lanzhou,Gansu,China between June 2011 and June 2020.Of these,85 patients had MPMTs.The clinical features,treatment factors,prevalence,and prognosis of this latter cohort were analyzed.RESULTS The incidence of MPMTs in patients with gastrointestinal malignant tumors was 1.05%(85/8059),including 83 double primary malignant tumors and two triple primary malignant tumors of which 57(67.06%)were synchronous MPMTs(SMPMTs)and 28(32.94%)were metachronous MPMTs(MMPMTs).The most frequent associations were found between the rectum colon cancers within the SMPMT category and the gastric-colon cancers within the MMPMT category.For the MMPMTs,the median interval was 53 months.The overall 1-,3-and 5-year survival rates from diagnosis of the first primary cancer were 91.36%,65.41%,and 45.97%,respectively;those from diagnosis of the second primary cancer were 67.90%,29.90%,and 17.37%,respectively.CONCLUSION MPMTs in the gastrointestinal tract have a high incidence and poor prognosis.Thus,it is necessary to perform both gastroscopy and colonoscopy in patients with gastrointestinal tumors.Multidisciplinary comprehensive diagnosis and treatment may improve the diagnosis rate and treatment efficiency of MPMTs.

文摘In this editorial,we comment on the article by Liu et al.Based on our analysis of a case report,we consider that early screening and recognition of primary nasal tuberculosis are crucial for patients undergoing treatment with tumor necrosis factor inhibitor(TNFi).While TNFi therapy increases the risk of reactivating latent tuberculosis,primary nasal tuberculosis remains rare due to the protective mechanisms of the nasal mucosa.Risk factors for primary nasal tuberculosis include minimally invasive nasal surgery,diabetes,and human immunodefi ciency virus.Patients with early symptoms such as nasal congestion,rhinorrhea,altered olfaction,epistaxis,or ulceration,and unresponsive to conventional antibiotics and antihistamines should undergo early rhinoscopy,possibly followed by repeated tissue biopsies and acid-fast bacilli culture when necessary.When diagnosis is challenging,it is essential to consider local tuberculosis epidemiology and the efficacy of diagnostic antituberculosis treatment.The preferred method for tuberculosis screening is the Interferon Gamma Release Assay,with a general recommendation for screening at 3 and 6 months after initial treatment and then every six months.However,the optimal frequency is not yet consensus-driven and may be increased in economically viable settings.
文摘Our hospital documented 214 cases of primary mediastinal tumor from May 1957 to July 1995. They were treated surgically, There were 184 benign cases (85. 98% ), and 30 malignant cases (14.02 % ). Among them, there were 63 cases of neurogenic tumor (29.43 % ), 48 cases of thymic tumor (22. 4% ), 41 cases of teratoid tumor (19. 16% ), 12 cases of bronchial cyst (5. 61% ), and 9cases of intrathoracic adenoma of thyroid (4. 21%). The authors mainiy discuss the early diagnosis,tumor variety, operating incisions, and operating essentials.
文摘AIM:To evaluate the diagnostic value of panoramic immersion B-scan ultrasonography(Pano-immersion B-scan,PIB)in complex retinal detachment(RD),persistent hyperplastic primary vitreous(PHPV)and intraocular tumors.METHODS:The clinical data of 44 patients collected from May 2012 to December 2019 in Chinese PLA General Hospital was retrospectively studied.All of these patients underwent PIB of the eye,because it was difficult to diagnose by routine ocular fundus examination,conventional ultrasound or/and ultrasonic biomicroscope(UBM)due to opacity of refractive media,pupillary occlusion,large involvement or special location of the lesion.The imaging features of difficult cases in PIB were analyzed.The diagnosis accuracy rating of PIB were evaluated and contrasted with conventional ultrasound or UBM by the standard of intraoperative diagnosis or/and pathological results.RESULTS:According to intraoperative diagnosis or pathological results as gold standard,among the 44 cases,there were 19 cases missed diagnosis,misdiagnosed or difficult-to-diagnose by conventional ultrasound or UBM,including 4 cases of long-standing RD difficult to diagnose,4 cases misdiagnosed,and 11 cases incompletely observed or miss diagnosed.The diagnostic accuracy rate of PIB and conventional ultrasound or UBM were 100%(44/44)and 56.82%(25/44),and the sensitivity of them were 100%and 56.82%.All the patients underwent PIB and were diagnosed as RD(15 cases),retinal and choroidal detachment(4 cases),subchoroidal hematocele(1 case),vitreous opacity and/or organic membrane formation(4 cases),PHPV(12 cases),iris and/or ciliary body tumors(3 cases),and choroidal tumors(6 cases).According to the intraoperative diagnosis or pathological results,the diagnostic coincidence rate of PIB was 100%,which was significantly higher than conventional ultrasound and UBM.CONCLUSION:PIB can help to accurately diagnose complex RD,PHPV,and intraocular masses with special location or/and excessive size.It has important diagnostic value for patients with equivocal findings at conventional ultrasound examination.
文摘BACKGROUND Primary hepatic carcinoma(PHC)has an insidious onset and is usually diagnosed in the middle and late stages.Although transcatheter arterial chemoembolization(TACE)is the preferred option for treating middle-and advanced-stage PHC,it has limited efficacy in killing tumor cells and poor long-term efficacy.TACE plus percutaneous microwave coagulation therapy(PMCT)is more effective than interventional therapy alone and can improve survival time.However,there are few reports on the effects of TACE and PMCT on serum marker levels and the prognosis of patients with advanced PHC.AIM To investigate the effect of PMCT+TACE on serum tumor markers and the prognosis of middle-late PHC.METHODS This retrospective study included 150 patients with middle-late PHC admitted to Zhongshan People’s Hospital between March 2018 and February 2021.Patients were divided into a single group(treated with TACE,n=75)and a combined group(treated with TACE+PMCT,n=75).Before and after treatment,the clinical efficacy and serum tumor marker levels[carbohydrate antigen 19-9(CA19-9),alpha-fetoprotein(AFP),and carcinoembryonic antigen(CEA)]of both groups were observed.The 1-year survival rates and prognostic factors of the two groups were analyzed.RESULTS The combined group had 21 and 35 cases of complete remission(CR)and partial remission(PR),respectively.The single group had 13 and 25 cases of CR and PR,decreased,with the decrease in the combined group being more significant(P<0.05).The 1-year survival rate of the combined group(80.00%)was higher than that of the single group(60.00%)(P<0.05).The average survival time within 1 year in the combined group was 299.38±61.13 d,longer than that in the single group(214.41±72.97 d,P<0.05).COX analysis revealed that tumor diameter,tumor number,and the treatment method were prognostic factors for patients with middle-late PHC(P<0.05).CONCLUSION TACE+PMCT is effective in treating patients with mid-late PHC.It reduces the levels of tumor markers,prolongs survival,and improves prognosis.
文摘Objective: Through this surgical series, we present the epidemiological and anatomical-clinical aspects and the surgical results concerning patients operated on for a primary cardiac tumor at the Abidjan Heart Institute. Materials and Method: This is a retrospective descriptive study covering the period of January 1982 to December 2022, based on the medical records of patients operated on for a primary cardiac tumor at the Abidjan Heart Institute. Results: Twenty-seven (27) patients underwent surgery for a primary cardiac tumor, including 14 women and 13 men with a mean age of 41.5 years (range 19 - 76 years). The main circumstances of discovery were exertional dyspnea, palpitation and syncope or pseudo-syncope. The main site was the septal wall of the left atrium. The diagnosis of myxoma was confirmed by pathological examination of the surgical specimen in 96.3% (n = 24) of the patients and it was a malignant large cell immunoblastic lymphoma of the myocardium in 3.7% (n = 1) of the patients. The mean largest diameter was 46.1 mm. The postoperative course was marked by an ischaemic stroke (n = 1);recurrence of a left atrial myxoma 5 years after the first tumor removal (n = 1). Two cases of death were noted, one due to the evolution of immunoblastic large cell lymphoma and the other due to an extracorporeal circulation accident. Conclusion: Almost all primary cardiac tumors operated on in Abidjan are myxomas. The circumstances of the discovery of these cardiac tumors are multiple and varied but dominated by exertional dyspnea, palpitation and syncope. Whatever their histological type, primary cardiac tumors are serious affections, in view of the haemodynamic and rhythmic disorders they cause.

文摘BACKGROUND Collision tumors of primary malignant lymphoma and adenocarcinoma in the colon are rare.Primary diffuse large B-cell lymphoma(DLBCL)–adenocarcinoma collision tumors are especially rare.CASE SUMMARY A 74-year-old woman presented with abdominal pain of 1 mo duration.Biopsy under colonoscopy revealed adenocarcinoma of the ascending colon.Subsequently,the patient underwent laparoscopic radical resection of right colon cancer with lymph node dissection.A collision tumor was found incidentally through postoperative pathological sampling.Genetic analysis showed a collision tumor of DLBCL with germinal center B-cell subtype and TP53 mutation,and adenocarcinoma arising in a tubulovillous adenoma in the colon,with BRAF mutation and mutL homolog 1 promoter methylation.The patient died 3 mo after surgery.To our knowledge,this is the 23rd reported case of collision tumor of colorectal adenocarcinoma and lymphoma.The mean age of the 23 patients was 73 years.The most common site was the cecum.There were 15 cases with followup data including 11 living and four dead with a 3-year overall survival rate of 71.5%.CONCLUSION Based on pathological and genetic analysis,surgery combined with chemotherapy or chemoradiotherapy may have good therapeutic effects for collision tumor.
文摘BACKGROUND Germ cell tumors(GCTs)account for 2%of human malignancies but are the most common malignant tumors among males aged 15-35.Since 1983,an association between mediastinal GCT(MGCT)and hematologic malignancies has been recognized.CASE SUMMARY We report a case in which malignant histiocytosis was associated with mediastinal GCTs.The clinical data of a male patient with MGCT admitted to Beijing Children's Hospital were collected retrospectively.The patient was first diagnosed according to imaging and pathological features as having MGCT,and was treated with surgery and chemotherapy.One year after stopping chemotherapy,imaging showed metastases in the right supraclavicular,mediastinum,hilar region and retroperitoneal lymph node,right pleura,right lung,and right para-cardiac margin.Pathological diagnosis of the liver nodular and hilar lymph nodes included systemic juvenile xanthogranuloma and Rosai-Dorfman lesions with malignant transformation(i.e.,morphological characteristics and immunophenotype of histiocytic sarcoma).Following diagnosis,the patient accepted chemotherapy with vindesine,cytarabine and dexamethasone.Positron emission tomography–computed tomography showed partial remission.The patient was followed-up for 10 mo after the diagnosis of malignant histiocytosis,and no sign of progression or relapse was observed.CONCLUSION Physicians should recognize the possibility of hematologic malignancies being associated with MGCT.Suitable sites should be selected for pathological examination.

文摘Objective:Triple-negative breast cancer(TNBC)is a heterogeneous and aggressive cancer.Although our previous study classified primary TNBC into four subtypes,comprehensive longitudinal investigations are lacking.Methods:We assembled a large-scale,real-world cohort comprised of 880 TNBC patients[465 early-stage TNBC(eTNBC)and 415 metastatic TNBC(mTNBC)patients]who were treated at Fudan University Shanghai Cancer Center.The longitudinal dynamics of TNBC subtypes during disease progression were elucidated in this patient cohort.Comprehensive analysis was performed to compare primary and metastatic lesions within specific TNBC subtypes.Results:The recurrence and metastasis rates within 3 years after initial diagnosis in the eTNBC cohort were 10.1%(47/465).The median overall survival(OS)in the mTNBC cohort was 27.2 months[95%confidence interval(CI),24.4–30.2 months],which indicated a poor prognosis.The prognostic significance of the original molecular subtypes in both eTNBC and mTNBC patients was confirmed.Consistent molecular subtypes were maintained in 77.5%of the patients throughout disease progression with the mesenchymal-like(MES)subtype demonstrating a tendency for subtype transition and brain metastasis.Additionally,a precision treatment strategy based on the metastatic MES subtype of target lesions resulted in improved progression-free survival in the FUTURE trial.Conclusions:Our longitudinal study comprehensively revealed the clinical characteristics and survival of patients with the original TNBC subtypes and validated the consistency of most molecular subtypes throughout disease progression.However,we emphasize the major importance of repeat pathologic confirmation of the MES subtype.
文摘BACKGROUND Rare liver tumors(RLTs)have an extremely low likelihood of forming,and some have been recorded only in isolated cases.The lack of normal clinical symptoms in RLTs makes preoperative diagnosis extremely challenging,which results in frequent misinterpretation.The present case report helps enhance our ability to recognize and treat uncommon liver tumor disorders.CASE SUMMARY We describe four distinct examples of rare liver tumor diseases.These cases were all true cases with no conventional clinical signs or imaging findings.In all patients,hepatic occupancy was discovered on physical examination,which raised the preoperative suspicion of hepatic cancer.All tumors were surgically removed,and postoperative histology and immunohistochemistry were performed to confirm the diagnosis.The first patient had primary hepatic fibrosarcoma.The second case involved a primary hepatic neuroendocrine tumors.These two patients had malignant liver tumors,and both had extremely satisfactory surgical outcomes.The third case involved focal hepatic steatosis,and the fourth case involved a single necrotic nodule in the liver.These two patients had benign liver tumors,but they had already undergone surgery and did not require any postoperative care.CONCLUSION The number of patients with RLTs is small,and the clinical and imaging results are vague.Preoperative diagnosis is challenging,and patients are sometimes mistakenly diagnosed with liver cancer,which leads to unnecessary surgical therapy in certain individuals.
文摘Although rare, intraneural hemangiomas should be considered in the differential diagnosis of peripheral nerve lesions. We report on a 59-year-old female patient, who was admitted to the hospital due to the discovery of bilateral breast masses for 3 months, there was no paresthesia or dyskinesia. The patient accidentally found a mass in the right upper mediastinum while completing a plain chest X-ray, initially suspected as a benign neurilemmoma on CT. Surgical resection and pathological analysis confirmed an intraneural hemangioma. Unexpectedly, the patient developed new-onset right upper limb numbness and paresthesia 3 months post-operatively, probably related to surgical nerve injury. This case underscores the importance of maintaining a broad differential for mediastinal masses, and the potential for iatrogenic neurological complications when managing these rare, yet vascular lesions.

文摘BACKGROUND Multiple primary malignant tumors(MPMTs)are rare type of cancer,especially when solid tumors are the first and lymphoma is the second primary malignancy.We report a patient with heterochronous MPMTs consisting of prostate cancer and rectal diffuse large B-cell lymphoma(DLBCL).CASE SUMMARY We report a 77-year-old male patient diagnosed with prostate cancer who was treated with radiation therapy and one year of endocrine therapy with bicalutamide(50 mg per day)and an extended-release implant of goserelin(1/28 d).Seven years later,rectal DLBCL with lung metastases was found.CONCLUSION Although rare,the possibility of prostate cancer combined with a double primary cancer of DLBCL can provide a deeper understanding.
文摘BACKGROUND Primary vaginal cancer is rare and most vaginal tumors are metastatic,often arising from adjacent gynecologic structures.Primary vaginal cancers are also more common among postmenopausal women and most of these are squamous cell carcinomas,with adenocarcinomas being relatively rare.Vaginal bleeding is the most common clinical manifestation of vaginal adenocarcinoma.About 70%of vaginal adenocarcinomas are stage I lesions at the time of diagnosis,for which radical surgery is recommended.However,more advanced vaginal cancers are not amenable to radical surgical treatment and have poor clinical outcomes.Optimal treatments modes are still being explored.Here,we report a rare case of stage IIb primary vaginal adenocarcinoma for which an individually designed vaginal applicator for after-loading radiotherapy was used to achieve good tumor control.CASE SUMMARY A 62-year-old woman presented to our clinic after 3 months of abnormal postmenopausal vaginal bleeding.Gynecological examination,computed tomography(CT),and positron emission tomography-CT showed a large mass(about 5 cm)on the anterior vaginal wall.Colposcopy biopsy confirmed adenocarcinoma of vaginal origin.After three cycles of carboplatin plus paclitaxel chemotherapy,the lesion partially shrunk.The patient then received external irradiation of 45 gray(gy)in 25 fractions,which further reduced the vaginal lesion,followed by after-loading radiotherapy of 30 gy in 5 fractions with an individually designed vaginal applicator.Three months later,magnetic resonance imaging showed a slight thickening CONCLUSION Primary vaginal adenocarcinoma is rare,and prognosis is poor in most vaginal cancers of locally advanced stages,which cannot be treated with radical surgery.Better tumor control can be achieved with an individualized vaginal applicator that allows administration of a higher radical dose to the tumor area while protecting normal tissues.
文摘Object.To study the clinical manifestations,diagnostic methods,surgical management ,and prognosis of various neurogenic mediastinal tumors.Method.One hundred and ten cases of neurogenic tumors of mediastinum were reviewed and retro-spectively analyzed.Results.Operative or hospitalization death happened in2cases,complications occurred in8cases,mostly were Horner’s syndrome or recurrent nerve paralysis.During the follow?up,there were2recur-rences in102benign tumors,and4cases of neurofibrosarcoma or malignant neurilemmoma died within3years postoperatively.Conclusion.Most mediastinal neurogenic tumors are benign.It is enough to establish diagnosis by chest X?ray and CT scan.There are different features in the clinical manifestations,diagnosing methods,and surgical management for the dumbbell tumors.Minimal invasive surgery and video?assisted thora-coscopy surgery(VATS)have a special value in treatment of the selected neurogenic mediastinal tumors.Benign neurogenic tumors rarely recur after complete resection,whereas malignant neurogenic tumors have poor prognosis.
文摘Background:The clinical manifestations of cardiac masses are diverse and lack specifi city.Here we report a cardiac mass detected by transthoracic echocardiography.Multimodality imaging and pathological fi ndings after the operation confi rmed the mass as mediastinal tuberculoma.Case presentation:A 45-year-old male patient was admitted to our hospital reporting chest tightness,weight loss,and dyspnea for 3 months after exercise.Transthoracic echocardiography showed that there were a large number of pericardial effusions and a soft tissue mass measuring 7.7 cm×4.5 cm in the upper mediastinum,which oppressed the right pulmonary artery and accelerated the blood fl ow of the left pulmonary artery.Contrast-enhanced ultrasonography showed degenerative inhomogeneous high enhancement of and an unclear boundary in the mass.Contrast-enhanced chest CT revealed punctate and patchy calcifi cation in and uneven enhancement of the mass and the lymph nodes around the aortic arch.The mass was diagnosed as a malignant mediastinal tumor.Pathological analysis of the mass revealed chronic granulomatous tuberculosis.The symptoms abated signifi cantly after antituberculosis treatment.The patient remained asymptomatic during follow-up.Conclusion:This report presents a rare case of mediastinal tuberculoma mimicking a malignant cardiac tumor.Multimodality imaging should be incorporated for differentiation of cardiac masses.
文摘Hydatid disease is caused by Echinococcus granulosus parasite. It is an endemic disease;particularly in many Mediterranean countries. The liver and the lungs are most frequently involved. Bone involvement is reported in 1% - 2% of the cases and about 50% of those are seen in the spine. Herein we report a case of primary spinal extradural hydatid cyst that caused paraplegia due to compression of the dorsal spinal cord and was diagnosed initially as case of lumber prolapsed intervertebral disc. The cyst was only discovered when the patient had progressive paraplegia and the preoperative provisional diagnosis was posterior mediastinal neurogenic tumor causing destruction of the pedicle and lamina of the fifth thoracic vertebra. Fortunately, she regained near full power after surgical treatment of her spinal cyst.
文摘Carcinoma of unknown primary (CUP) is occasionally encountered in clinical oncology. Wide variation exists in CUP. We herein report a rare case of CUP of a mediastinal lymph node. A 61-year-old man with dermatomyositis was referred to our hospital for treatment of mediastinal adenopathy and gastric cancer. Biopsy of both lesions showed that they were histologically different from each other. Mediastinal lymphadenectomy and total gastrectomy were performed for a definitive diagnosis and radical cure. Pathological examination revealed two distinctly different disease processes. The patient underwent postoperative chemotherapy for residual gastric cancer. Twenty months postoperatively, he is alive with cancer. Although CUP usually has a poor prognosis, surgical treatment of metastatic mediastinal lymph node CUP is a feasible therapeutic option.
文摘Ganglioneuroma is an extremely rare tumor that is derived from neural crest. Many ganglioneuroma cases are detected incidentally unless they are large enough to cause compressive symptoms. We report an 18-year-old patient with posterior mediastinal ganglioneuroma which was abutting the descending aorta. The patient underwent successful resection by thoracoscopic approach and was followed up for one year with no complications. In summary, a detailed review with experts in both radiology and pathology is mandated to diagnose these tumors. Informed consent was obtained from the patient.
