Abstract
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.关键词
