[Adult neuroblastoma of the adrenal with intraatrial tumor thrombus: report of a case].

A case of adult neuroblastoma of the right adrenal with tumor thrombus extending into the right atrium is reported. Because of right heart failure, the tumor thrombus in the right atrium was removed under the cardiopulmonary bypass. The histopathological examination of the tumor thrombus revealed neuroblastoma. Fourteen days after the first operation, the adrenal tumor, right kidney and tumor thrombus remaining in the vena cava were removed to prevent the recurrence of right heart failure. Two courses of chemotherapy and radiation were given postoperatively and the patient was doing well. Eight months after the second operation, however, the patient died of multiple metastases of the bone and liver.
