The authors analyzed 26 cases of primary retroperitoneal neoplasia confirmed by surgery or pathology and performed more than 2 items in CT, MRI, and angiography. Among them, 8 were examined in 3 cases, and the remaining 2 were examined. 5 cases of leiomyosarcoma, 7 cases of neurogenic tumor, 4 cases of liposarcoma, 3 cases of malignant fibrous histiomas (MFH), 5 cases of malignant lymphoma, 1 case of lipoma and synovial sarcoma.
