Adrenal myelolipoma: diagnosis and management.
BACKGROUND
Adrenal myelolipomas are benign lesions that contain hematopoietic and fatty elements. They are usually hormonally inactive and asymptomatic until they reach large sizes. With the routine use of cross-sectional imaging, these lesions are now being discovered with increasing frequency.


METHODS
We performed a comprehensive review of the literature using the PubMed database containing the key word adrenal myelolipoma.


RESULTS
We identified 492 articles written from 1956 to 2006 and reviewed 93 in detail including the authors' own experience. In this review, we highlighted the salient diagnostic features of adrenal myelolipomas and offered a guide for management of these benign lesions.


CONCLUSIONS
Adrenal myelolipomas may grow over time, but they can usually be followed without surgical excision. In some cases, very large myelolipomas can present with pain and can be confused with necrotic adrenal carcinomas, thus necessitating their surgical removal.
