摘要
目的总结原发性腹膜后肉瘤的超声图像特征。方法回顾性分析经穿刺活检或手术病理证实的47例原发性腹膜后肉瘤患者的声像图资料,总结腹膜后肿瘤的数目、大小、边界、形态、回声特点、血流情况及其与邻近组织、器官的关系等。结果47例原发性腹膜后肉瘤患者,经病理证实为脂肪肉瘤29例,平滑肌肉瘤13例,横纹肌肉瘤4例,尤文肉瘤1例。其中单发42例,多发5例;肿瘤最大直径2.0~55.0 cm,平均(14.3±9.6)cm。声像图表现为低回声32例,稍强回声8例,混合回声7例;内部回声不均匀16例,肿瘤内合并无回声区12例;肿瘤内伴斑片状强回声5例;边界较清楚26例,边界不清楚21例;形态规则15例,形态不规则32例。CDFI示肿瘤内可探及丰富点线状血流信号35例,未探及明显血流信号12例。肿瘤不同程度累及周边组织、器官18例,其中伴腹膜后淋巴结转移4例,伴双侧髂总静脉及下腔静脉内瘤栓形成1例。结论原发性腹膜后肉瘤的超声表现有一定特征,肿瘤体积常较大,腹膜后边界较清楚,为形态不规则的团状低回声,部分合并无回声区或伴斑片状强回声,CDFI示其内多可探及丰富的点线状血流信号。
Objective To summarize the ultrasonic characteristics of the primary retroperitoneal sarcoma.Methods Ultrasonographic data of 47 patients with primary retroperitoneal sarcoma confirmed by biopsy or surgical pathology were retrospectively analyzed,the number,size,boundary,shape,echo characteristics,blood flow features of retroperitoneal sarcoma and its relationship with adjacent tissues and organs were summarized.ResultsAmong 47 patients with primary retroperitoneal sarcomas,29 cases were pathologically confirmed as liposarcomas,13 cases as leiomyosarcomas,4 cases as rhabdomyosarcomas,and 1 case as Ewing’s sarcomas.Singe lesion was found in 42 cases,while multiple lesions were found in5 cases.The maximum diameter of all tumors were 2.0~55.0 cm,and the average maximum diameter was(14.3±9.6)cm.The sonogram showed 32 cases of hypoechoic,8 cases of slightly hyperechoic and 7 cases of mixed echoic.16 cases of uneven internal echo,12 cases of anechoic area in the tumor,and 5 cases of calcification in the tumor.26 cases with clear boundary,and 21 cases with unclear boundary.15 cases with regular morphology,while 32 cases with irregular morphology.CDFI showed abundant dot-line blood flow signals in 35 cases,and no obvious blood flow in the 12 cases.18 cases invaded peripheral organs with different degrees,4 cases accompanied with retroperitoneal lymph node metastasis,and 1 case with tumor thrombosis in bilateral common iliac vein and inferior vena cava.ConclusionPrimary retroperitoneal sarcomas have certain ultrasonic characteristics.The tumors are often present as large size,and grayscale ultrasound usually showed as well-defined hypoechoic masses with irregular shape in the retroperitoneum.Some tumors are associated with anechoic areas or patchy strong echoes,and abundant dot-line blood flow signals can be detected in majority of retroperitoneal sarcomas by CDFI.
