Preoperative evaluation for intraductal spread by CE-MRI should be more useful than by MMG for breast cancer. When making the surgical decision regarding excision range, particular attention should be paid to this consideration for patients with larger-sized cancer tumors.

The pattern of TIC could be used to predict lymphatic spreading associated with lymph node metastasis prior to surgery as well as to detect malignancy. Therefore, a more detailed evaluation should be made to identify the presence of lymphatic spreading in patients with a malignant pattern of TIC.

A63-year-old manwith symptomsof 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 rhabdomyosarcomawith 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)
