Abstract
A 41-year-old woman was admitted to our hospital with the chief complaints of right lower abdominal pain andedema in the lower extermities. The diagnosis of gallstone disease associated with a retroperitoneal tumor of the infiltrated range was was made by using ultrasonography, computed tomography angiography. Primary tumor in the inferior vena cava or invasion of retroperitoneal tumor was suggested by postcavarography and magnetic resonanse imaging test. First of all, cholecystectomy was performed because of the complication of cholelithiasis. The tumor was a yellowish-white massive one with approx. 6 cm in diameter sitting to the lower surface of the liver, and internal and upper regions of the right kidney, and existed so as to eject from the inferior vena cava. The combined resection of the right kidney was performed, because resections of the partial postcaval walls and the tumor, and its ablastions were difficult. The double lineserial cross suture of the amputation stump of the inferior vena cava was carried out. The chemotherapy was concomitantly used as an auxotherapy. The postoperative couse was favorable, and the patient is under observation on ambulatory basis as of now progressed for 4 months. Eighteen cases of primary leiomyosarcoma in theinferior vena cava including this case have been reported in our country so faras we studied, and we also presented a discussion of some references because of its seldom occurrence.
