A right adrenal tumor was found incidentally during abdominal computed tomography exam in a 51-year-old female patient, who had had diabetes and hypertension for more than 10 years. The computed tomography scan was arranged for possible pancreatic lesion by a neurologist. Norepinephrine level was high in the plasma and urine. ⋯ Therefore, adrenal cortical adenoma with subclinical Cushing's syndrome was highly suspected; however, further imaging studies, including magnetic resonance image and 131I-6beta-iodomethylnorcholesterol adrenal scintigraphy failed to discriminate an additional tumor. After right adrenalectomy, a small adrenal cortical adenoma and a large pheochromocytoma were noted. This is an extremely rare case of an adrenal incidentaloma consisting of both medullary and cortical tumors in the same gland.
