A 63-year-old man with symptoms of obstruction of the inferior vena cava was examined by computed tomography, ultrasound imaging and angiography. Examination revealed a tumor in the inferior vena cava, and transvenous biopsy revealed a rhabdomyosarcoma. The tumor was surgically resected and was easily separated from the surrounding tissues. Nevertheless, a local recurrence developed 43 days after the operation, and the patient's condition deteriorated rapidly. Hepatomegaly and ascites believed to represent the Budd-Chiari syndrome were noted. The patient died on the 163rd postoperative day. Autopsy revealed a tumor extending from the inferior vena cava just above the right renal vein to the right atrium and involving the lobus caudatus of the liver. Clinically, the tumor was thought to have arisen from the middle segment of the inferior vena cava. However, a diagnosis of primary hepatic rhabdomyosarcoma with extrahepatic growth could not be excluded. Only 12 cases of primary liver rhabdomyosarcoma have been reported, and none of those patients demonstrated Budd-Chiari syndrome. Our patient, diagnosed as rhabdomyosarcoma with secondary Budd-Chiari syndrome, is believed to be the first such report.(Internal: Medicine 32: 67-71, 1993)
