[Pheochromocytoma manifested by traumatic adrenal hemorrhage].
The presentation of pheochromocytoma is quite variable. We report a case of previously undiscovered pheochromocytoma which was manifested by traumatic retroperitoneal hemorrhage. A 79-year-old man fell from his bicycle and was admitted to the emergency room complaining of right flank pain. Enhanced computed tomography (CT) revealed hemorrhage around the right adrenal gland. Since the plasma catecholamine levels were elevated, we suspected the presence of pheochromocytoma. After absorption of the hematoma, the tumor appeared clearly. The diagnosis of pheochromocytoma was confirmed through urine catecholamine testing and 131I-MIBG scintigraphy. Six months after the injury, the tumor was surgically resected. Traumatic hemorrhage of pheochromocytoma is extremely rare; only 3 cases have been reported in the literature.
