输尿管癌与输尿管子宫内膜异位症的MSCT鉴别

Differential Diagnosis of Ureteral Carcinoma and Ureteral Endometriosis by MSCT

目的探讨MSCT在输尿管癌与输尿管子宫内膜异位症的鉴别诊断中的应用价值。资料与方法回顾性分析经病理证实的5例输尿管子宫内膜异位症和12例输尿管癌患者的CT资料。结果5例输尿管子宫内膜异位症CT表现为腔外软组织肿块4例、腔内充盈缺损1例,合并附件囊性灶3例。12例输尿管癌CT表现为管壁增厚3例、腔内充盈缺损5例和腔外肿块4例,合并后腹膜淋巴结肿大3例。结论MSCT在鉴别输尿管癌与输尿管子宫内膜异位症方面具有一定的临床应用价值。

Objective To assess the value of MSCT in the differential diagnosis of ureteral carcinoma and ureteral endometriosis. Materials and Methods The CT data of 5 patients with ureteral endometriosis and 12 patients with ureteral carcinoma confirmed by pathology were retrospectively analyzed. Results The CT appearances of ureteral endometriosis included extraluminal mass（3 cases） ,intraluminal filling defect（1 case） ,and concurrent with ovarian cysts （3 cases）. The CT appearances of ureteral carcinoma were ureteral wall thickening（3 cases）, intraluminal filling defect（5 cases）, extraluminal mass （4 cases） , and retroperitoneal lymph node swell（3 cases）. Conclusion MSCT play a certain role in differential diagnosis of ureteral carcinoma and ureteral endometriosis.
