This is a report of the occurrence of familial ectopic pheochromocytoma in two brothers, whose father had bilateral adrenal pheochromocytoma. Both brothers complained of hypertension. In the first case, a 22-year-old man presented with much higher than normal norepinephrine. Abdominal CT and chest CT scanning and 123I-MIBG scintigraphy revealed an extraadrenal tumor in the chest on the bilateral adrenal Brands. Bilateral adrenectomy was performed. In the second case, the 20-year-old brother was found to have an abdominal mass that was diagnosed as ectopic pheochromocytoma originating in the intra-abdominal paraaorta according to abdominal CT scanning and 131I-MIBG scintigraphy. The tumor was resected.
