目的：探讨原发性腹膜后恶性肿瘤的CT诊断要点,以提高对原发腹膜后恶性肿瘤的认识,评价CT在明确腹膜后恶性肿瘤诊断中的价值。方法回顾性分析经病理证实的26例腹膜后恶性肿瘤的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①26例中,21例CT定位与手术部位相符合,其定位的准确性为80.8%(21/26)；11例CT定性结果与病理组织学结果完全相符,准确性为42.3%(11/26)。②脂肪肉瘤9例,平滑肌肉瘤1例,恶性纤维组织细胞瘤3例,恶性孤立性纤维性肿瘤1例,胃肠外恶性间质瘤1例,尤文氏肉瘤1例,神经母细胞瘤2例,恶性神经鞘瘤1例,恶性嗜铬细胞瘤1例,节神经母细胞瘤1例,恶性神经内分泌瘤1例,混合生殖细胞肿瘤1例,卵黄囊瘤1例,胚胎性横纹肌肉瘤1例,精原细胞瘤1例。结论腹膜后恶性肿瘤种类多,大多数CT表现不具有典型的特异性,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 malignant primary retroperitoneal tumor,in order to improve the diagnostic accuracy of this kind of tumors. Methods The CT findings of 26 cases with primary retroperitoneal malignant tumors proved by pathology were analyzed retrospectively. The location,shape,size and degree enhancement of tumors were analyzed and compared with pathological results. Results Of the 26 primary retroperitoneal malignant tumors, the accuracy of CT localization diagnostic rate were 80. 8% (21/26);the qualitative diagnostic accuracy was 42. 3%(11/26). There were liposarcoma in 11 ca-ses,leiomyosarcoma in 1 cases, malignant fibrous histiocytoma in 3 cases, malignant solitary fibroustumor in 1 case, extra-gastro-intestinal stromal tumors in 1 case,Ewing's sarcoma in 1 case, neuroblastoma in 2 cases, malignant neurinoma in 1 cases,malig-nant pheochromocytoma in 1 case, ganglioneuroblastoma in 1 case, malignant neuroendocrine tumors in 1 case, mixed germ cell Tumors in 1 case, yolk sac tumor in 1 case, embryonal rhabdomyosarcoma in 1 case, spermatocytoma in 1 case. Conclusion Due to the variety of malignant retroperitoneal tumor, most of them do not have the typical CT appearance, CT plays an important role in location,qualitative diagnosis and differential diagnosis of primary retroperitoneal tumor.
