[Pheochromocytoma with retroperitoneal hemorrhage after abdominal trauma]

A 35-year-old man was delivered to the emergency room complaining of right flank pain because of blunt abdominal trauma sustained while playing baseball. Enhanced computed tomography (CT) revealed a right adrenal mass and fluid collection around the mass. We diagnosed the mass as pheochromocytoma by endocrinological examination and radioisotopical imaging test. After absorption of the hematoma three months after the injury, laparoscopic right adrenalectomy was performed. He had an uncomplicated postoperative course without supplementation of catecholamine. Pathological findings were compatible with pheochromocytoma. Eight months after the operation, he had no evidence of recurrence.
