Article Abstract

A case of retroperitoneal liposarcoma that was removed after transarterial embolization is reported. A 62-year-old man was admitted with body weight loss and general fatigue. Computed tomography revealed an extrarenal tumor, 27 x 17 x 11 cm in size, in the left retroperitoneal space. Arteriography revealed that the hypervascular tumor was fed from the left renal artery, the left adrenal artery and the left lumber arteries (L1-L4). At first the patient underwent transarterial embolization of the left renal artery and the left lumbar arteries (L1, L3, L4). Twenty-two days later he underwent surgical excision of the tumor with combined resection of the left kidney and the descending colon. The resected tissue weighed 2,500 g. Histological examination revealed liposarcoma, pleomorphic type. His postoperative course was uneventful, and he has remained free of disease for 15 months.
