Summary	A 34-year-old man with MEN2A was presented with recurrence of thyroid medullary carcinoma. A preoperative CT scan revealed a left adrenal mass. 123I-MIBG study showed increased accumulation in the left adrenal mass, but no excessive secretion of catecholamines, and the preoperative diagnostic criteria for pheochromocytoma were not met. Because of the MEN2 patient, it was reasonable to diagnose the left adrenal mass as a pheochromocytoma, an alpha-blocker was administered preoperatively according to the perioperative management of pheochromocytoma. During the operation, the patient's blood pressure elevated due to the surgical maneuver, but antihypertensive treatment by alpha-blocker was effective, and the operation could be completed safely. Even in pheochromocytoma, endocrine function tests may not demonstrate excessive catecholamine secretion, and perioperative management based on comprehensive clinical findings is important to ensure safe treatment.
