von Hippel-Lindau 病に合併した両側褐色細胞腫の1例

A case of bilateral pheochromocytomas with von Hippel-Lindau's disease (VHL) is reported. A 46-year-old woman who had hyperglycemia was admitted to our hospital because of abdominal tumors. Her elder sister and niece had been diagnosed as VHL. Ultrasonography, CT, and MRI revealed bilateral adrenal tumors. Noradrenaline levels in serum and urine were elevated and 131I-MIBG scintigraphy showed accumulation in bilateral adrenal glands. Moreover, she had bilateral renal cysts and cerebellar hemangioblastoma. Bilateral adrenalectomies were performed and pathological diagnosis was pheochromocytoma. This is the seventh case of bilateral pheochromocytomas with VHL reported in Japan.
