A 64-year-old female patient had been receiving hemodialysis since June 2008. A left adrenal mass, 2.5 cm in diameter, was incidentally found by screening computed tomography at the initiation of hemodialysis. Plasma epinephrine and norepinephrine were increased to 1.21 ng/ml and 4.71 ng/ml, respectively. In the scintiscan using ¹²³I-metaiodobenzylguanidine (MIBG), accumulation of the radionuclide in the left adrenal tumor region was confirmed. Laparoscopic left adrenalectomy was performed without peri-operative complications under the diagnosis of left pheochromocytoma. The elevated catecholamines and the blood pressure were restored after surgery.
