Giant hemorrhagic myelolipoma in a patient with sickle cell disease

Adrenal myelolipoma is a rare, benign tumor consisting of adipose tissue and hematopoetic elements. It is generally diagnosed as an incidental finding due to its nonfunctioning, asymptomatic nature (Meaglia and Schmidt J Urol 147:1089, 1992). With increasing size, however, as seen in this case, myelolipomas can cause flank pain and abdominal distention. This lesion was diagnosed in a young male with sickle cell disease during a vaso-occlusive crisis.
