Small myelolipomas generally do not produce symptoms, and do not require treatment. Ongoing surveillance of these lesions by a doctor is recommended. Surgical excision (removal) is recommended for large myelolipomas because of the risk of bleeding complications.

Myelolipoma ("myelo-", from the ancient greek "μυελός", marrow; "lipo", meaning "of, or pertaining to, fat; "-oma", meaning tumor or mass") is a benign tumor-like lesion composed of mature adipose (fat) tissue and haematopoietic (blood-forming) elements in various proportions.

Myelolipomas can present in the adrenal gland, or outside of the gland.
