摘　　要：目的探讨原发性腹膜后肿瘤的螺旋CT诊断价值。方法回顾性分析32例经临床手术、病理证实的原发性腹膜后肿瘤螺旋CT资料,4例作平扫,28例行平扫加增强扫描。结果32例中良性肿瘤15例,恶性肿瘤17例,其中间叶组织来源16例,11例为恶性,神经组织来源10例,3例为恶性,残余胚胎组织来源3例,均为良性,来源不明3例,均为恶性。CT定位正确28例(87.5%),定性正确20例(62.5%)。结论原发性腹膜后肿瘤种类繁多,螺旋CT对于原发性腹膜后肿瘤的定位、定性提供明确的影像学依据。Objective To evaluate the helical CT diagnostic value of primary retroperitoneal neoplasm（PRN）. Methods 32 cases of PRN confirmed by operation and pathology were retrospectively analyzed. Plain and enhanced CT scan were perfomed in 28 cases,and only 4 cases underwent plain CT scans. Results Of 32 cases,15 were benign tumor and 17 cases were malignant tumor.Among them ,16 cases were mesenchymal tissue-origin（11 cases were malignant neoplasm）, 10 cases were nervous tissue-origin（3 cases were malignant neoplasm）,3 cases were rudimental embryonal tissue-origin（all benign）, and the source of unknown-origin were 3cases（all malignant neoplasm）.To be correctly localized was 28 cases（87.5%） and correctly qualitative diagnosis of the tumor was 20 cases （62.5%） by CT before operation. Conclusion PRNs have many typies, helical CT provides informations in both position and characteristics before operation.
