Adrenal Myelolipoma

Adrenal myelolipoma is a benign tumor composed of mature adipose tissue and hematopoietic elements. Myelolipomas usually occur in the adrenal gland, but have been identified in the presacral area, renal sinus and hilum, greater omentum, paravertebral area, and pulmonary bronchus. Rarely, simultaneous adrenal and extra-adrenal myelolipomas occur. Adrenal adenomas usually are solitary, but bilateral adrenal myelolipomas are reported. Adrenal myelolipomas affect males and females similarly and most often affects middle-aged adults, although it may occur over a wide age range. Approximately half the cases are asymptomatic, often incidental findings with characteristic imaging features.
