A sixty-four-year-old Japanese female with right adrenal myelolipoma was treated in our clinic. There were no specific subjective complaints. Routine laboratory data of this patient and endocrinological examination revealed no abnormality. During the routine ultrasonography tests, a round shaped tumor of approximately 60 mm in diameter was evidenced in the right adrenal area. The tumor showed three characteristics; 1) it was well-demarcated, 2) hyperechoic and 3) heterogeneous. These findings are in accord with the gross appearance of the resected tumor. Adrenal myelolipoma is rare with only 14 cases reported in Japan. The majority of cases were diagnosed by drip infusion pyelography, the initial symptoms being hematuria and abdominal pain. Careful observation of the findings on ultrasonography should make feasible a preoperative diagnosis at the early stage of this disease. At present 18 months postoperatively, the patient is doing well.
