[Bilateral pheochromocytomas with von Hippel-Lindau disease: a case report]

A case of bilateral pheochromocytomas with von Hippel Lindau disease (VHL) is reported. A 32-year-old man visited Kumamoto Red Cross Hospital for further examination of hypertension. Computed tomography revealed bilateral adrenal tumors and noradrenalin levels in serum and urine were elevated. Suspecting bilateral pheochromocytoma, he was reffered to our hospital for further examination and treatment. 131I-MIBG scintigraphy showed accumulation in bilateral adrenal glands. Moreover, he had cerebellar and spinal hemangioblastomas. Bilateral adrenalectomies and left nephrectomy were performed because tumor thrombus extended into the left renal vein, and pathological diagnosis was pheochromocytoma. His sister had been diagnosed as VHL disease. We diagnosed the patient as VHL disease because of the existence of cerebellar and spinal hemangioblastomas, bilateral pheochromocytomas, missense mutation and his family history. This is the eleventh case of bilateral pheochromocytomas with VHL disease reported in Japanese literatures.
