摘要
目的探讨腹膜后原发性肿瘤的CT特点,试图进一步提高对该类病变的认识水平。资料与方法回顾性分析经病理证实的28例腹膜后肿瘤的CT图像,观察肿块的位置、形态、大小及强化程度,并结合病理结果分析腹膜后肿瘤的CT特点。结果脂肪肉瘤3例,平滑肌肉瘤4例,恶性纤维组织细胞瘤3例,胃肠外恶性胃肠间质瘤2例,血管平滑肌脂肪瘤1例,神经鞘瘤4例,副神经节瘤2例,嗜铬细胞瘤3例,神经内分泌肿瘤1例,皮样囊肿1例,脉管瘤3例,囊性淋巴管瘤1例。其CT表现各不相同,CT定位腹膜后的准确率为71.42%(20/28),其中准确定性率为21.42%(6/28)。另有8例错误定位于腹膜后的脏器。结论腹膜后肿瘤种类多,其CT表现有很多重叠,但CT对腹膜后肿瘤的定位诊断率较高,对定性诊断及鉴别诊断也有一定的价值。
Objective To discuss the CT appearance of primary retroperitoneal tumor,in order to improve the diagnostic accuracy of this kind of tumors.Materials and Methods The CT findings of 28 cases with primary retroperitoneal tumor confirmed by pathology were analyzed retrospectively.The location,shape,size and degree enhancement of tumors were analyzed and compared with pathological results.Results There were liposarcoma in 3 cases,leiomyosarcoma in 4 cases,malignant extragastrointestinal tumors in 2 cases,malignant fibrous histiocytoma in 3 cases,angiomyolipoma in 1 case,schwannoma in 4 cases,paraganglioma in 2 cases,pheochromocytoma in 3 cases,neuroendocrine tumors in 1 case,dermoid cyst in 1 case,vascular tumor in 3 cases.These tumors had different CT appearance.The accuracy of location was 71.42%（20/28）,the qualitative diagnostic accuracy was 21.42%（6/28）.Conclusion CT plays an important role in location,qualitative diagnosis and differential diagnosis of primary retroperitoneal tumor.
