Abstract
Myelolipoma is a uncommon benign tumor of mesenchymal origin which consists of mature adipose tissue and normal hematopoietic cells. It occurs most often in adrenal gland [1] while extraadrenal (most often in the retroperitoneum) myelolipomas are also reported [2]. To date, most cases are asymptomatic or have epigastric pain. Acute hemorrhage is the most dramatic manifestation of adrenal myelolipoma; though, it is a rare entity. Hemorrhagic shock due to adrenal myelolipoma, to our knowledge, was far less mentioned so far. Myelolipoma accompanied by acute hemorrhage and calcification can complicate making the image-based diagnosis. Computed tomography frequently demonstrates large amounts of fat with areas of interspersed higher-attenuation tissue [3]. It is difficult to differentiate giant adrenal or extraadrenal myelolipomas from other fat-containing soft-tissue masses such as lipoma, liposarcoma, myolipoma, teratoma and an exophytic angioliposarcoma of the kidney [4].
