摘要
目的:探讨腹膜后与肠系膜囊性肿块(RMCM)的CT表现及CT诊断价值。方法:回顾性分析26例良性肿瘤、13例恶性肿瘤和46例非肿瘤病变的CT资料。结果:共有34个"无"壁型、55个均匀薄壁型、6个薄壁结节型和18个不均匀厚壁型囊性病灶。单房84个,多房29个。肿瘤最大径平均为8.5cm。多数良性病变呈圆形或类圆形、边界清晰、壁薄而均匀。恶性肿瘤通常壁厚而不均匀、边界不清楚。结论:RMCM病理类型多样,CT在肿瘤定位、明确范围与良恶性鉴别上有较大价值,但明确其组织来源上尚有一定困难。
Objective：To discuss the CT features and diagnostic value of retroparitoneal and mesenteric cystic masses（RMCMs）. Methods： CT findings of 85 cases with pathologically-proved primary benign tumors（n = 26 ）, malignant tumors （n = 13） and non-tumor masses （n= 46） were retrospectively analyzed. Results：On CT scans,there were 34 cystic lesions without visible wall, 55 with even thin wall and 18 with uneven thick waU as well as 6 lesions hating even thin wall and small mural nodules. The maximum diameter of RMCMs was averagely 8.5cm. Eighty four masses were unilocular and twenty nine were multilocular. Always with regular contour,even thin wall and well-defined margin, most of benign RMCMs were round or oval. Malignant RMCMs had an ill-defined margin and an uneven thick wall. Conclusion： CT is very helpful to define the site, extent and nature of RMCMs, and may suggest the pathological type of certain tumors. But, as for majority of RMCMs, CT is difficult to definite its histological origin because the pathological types of RMCMs are multiplieate.
