Figure 8c. Myelolipoma. (a) US scan shows a hyperechoic, well-limited mass of the right adrenal gland. (b) CT scan obtained after injection of contrast material shows a well-defined mass with hypoattenuating areas, which indicate a fat content. (c) Spin-echo T1-weighted MR image (690/12) shows high signal intensity in some areas of the tumor (arrows). This high signal intensity is comparable with that of fat. (d) Photograph of the gross specimen shows an association of soft-tissue (*) and fatty (arrows) components.
