Malignant Pheochromocytoma with Multiple Hepatic Metastases Treated by Chemotherapy and Transcatheter Arterial Embolization.

A 62-year-old Japanese male developed multiple hepatic metastases two years after resection of pheochromocytoma of the right adrenal gland. Transcatheter arterial embolization (TAE) was performed for the purpose of the treatment of hepatic metastases resistant to 27 cycles of combined chemotherapy consisting of cyclophosphamide, vincristine, and dacarbazine. After TAE, the hepatic metastatic lesions decreased in size and hypertension passed its crisis. The present case suggests the utility of TAE for multiple hepatic metastases under careful blood pressure monitoring.
