摘要
目的 :通过分析 2 9例腹膜后良性肿瘤的CT表现 ,探讨CT对腹膜后良性肿瘤的诊断价值。方法 :回顾性分析16例神经源性肿瘤、6例间叶组织源性肿瘤、5例囊肿及 2例胚胎残余组织源性肿瘤的CT资料。结果 :肿瘤最大径平均为10 .9cm。多数呈圆形或类圆形、轮廓光整、边界清晰。共有脂肪密度肿块 3例 ,囊性肿块 10例 ,囊实混合性肿块 4例 ,非均匀实质性肿块 6例及均匀实质性肿块 6例。结论 :腹膜后良性肿瘤具有一定的CT特征。
Objective:To evaluate the diagnostic value of CT in benign retroperitoneal tumors (BRTs).Methods:CT findings of 29 cases with pathologically-proved BRTs were retrospectively analyzed.The neoplasms included neurogenic tumors (n=16),mesoblastic tumors (n=6),cyst (n=5) and residual embryonic tumors (n=2).Results:The maximum diameter of BRTs was averagely 10.9cm.Always with regular contour and well-defined margin,the most of BRTs were round or oval.The lesions presented as fat-density (n=3),cystic (n=10),cystic-solid (n=4),nonhomogeneous solid (n=6) or homogeneous solid (n=6) masses on CT scans.Conclusion:BRTs carries certain CT features.CT scan is very helpful to define the site,extent and nature of BRTs.
