摘要
目的探讨肝脏包囊虫病的临床特点及CT诊断价值。方法对49例(女32例,男17例;年龄11岁～74岁,平均40.5岁)经临床和病理组织学证实的肝脏包囊虫病的CT征象进行了回顾性分析。全部病例行腹部CT平扫,5例又接受了CT增强扫描。结果49例中,细粒棘球蚴见于48例,泡状棘球蚴见于1例。病变部位以肝右叶最多(49%),其次是肝左叶(31%)以及肝左、右叶或尾叶并发(20%)。细粒棘球蚴的CT表现有5种类型,诸如单纯型,母子囊型,多囊型,混合型,以及钙化型。包虫囊肿感染的CT表现为内外囊分离,囊壁增厚,囊内小气泡影及囊内彩带征。泡状棘球蚴的CT平扫与增强扫描均无特征,诊断较困难。结论CT扫描对肝脏包囊虫病具有很高的诊断准确率,甚至CT平扫即可做出准确的定位诊断,对感染的肝包虫囊肿的诊断颇有价值。
Objoctive To investigate the clinical characteristics of hepatic eehinococeosis and the diagnostic value of CT for it. Methods CT findings of 49 patients（32 women, 17 men; aged 11 -74 years; mean age, 40. 5 years ）with clinically and histopathologieally proved hepatic eehinoeoceosis were analyzed retrospectively. All patients underwent CT scans of the abdomen without contrast agent, of them, 5 patients underwent additional enhanced CT scans with contrast agent. Results Among 49 eases, granulosus eehinococeosis was found in 48 eases, alveolar echinoeoceosis in 1 ease. In the ease of pathogenic locations, the lesions in right lobes and of left lobes liver comprised 49 % and 31%, respectively. Whereas complicated lesions in right and left lobes or tail lobes of liver comprised 20 %. On CT images , granulosus eehinocoeeosis presented 5 patterns such as simple cyst , mother-danghter-cyst, multiple cyst, mixed cyst, and calcified cyst. CT findings of infective hydatid cysts were separation between inside cysts and outside cysts, thickening of cystic wall, and intraeystie small air bubble and “color-bar”sign. CT scans of alveolar echinococcosis, either plain scan or enhanced scan, showed not any characteristic finding and therefore the diagnosis was difficult. Conclusion CT scans have high accuracy in the diagnosis of hepatic eehinoeoceosis, even CT plain scan can make the locative diagnosis. Simultaneously, CT scan has an important value for diagnosing the infective hydatid eysts.
