Clinics in diagnostic imaging (43). Right adrenal myelolipoma

A 53-year-old woman who presented with drug-induced jaundice and urinary tract infection was incidentally found to have a large abdominal mass. Radiographs and ultrasonography showed a large fatty mass located between the right lobe of the liver and the right kidney. Diagnosis of right adrenal myelolipoma was made on computed tomography. The patient was treated conservatively. The causes of large fatty masses of the abdomen in adults are discussed, with emphasis on the imaging appearances of myelolipoma, renal angiomyolipoma, cystic teratoma and liposarcoma.
