An asymptomatic 34-year-old woman was hospitalized for an adrenal tumor that had been discovered unexpectedly on ultrasonographic examination of the abdomen. The tumor mass appeared as a highly echogenic lesion on ultrasonography and had the same CT value as water on CT examination. Physical findings were not typical for any known pathologic entities. Angiographic findings were not significant. The resected tumor, which was reddish in color, fairly soft, and 2 cm in diameter, proved to be a typical myelolipoma on histologic examination. Microscopically, most of the lesion was composed of hypercellular hematopoietic tissue, thus explaining why the CT image was not compatible with the typical myelolipomas so far reported.
