A case of adrenal myelolipoma diagnosed by fine needle aspiration (FNA) biopsy is reported. The FNA smears contained the diagnostic picture of mature adipose tissue intermixed with hematopoietic elements, including megakarycytes. The FNA diagnosis was histologically confirmed by study of the resected tumor. This case appears to be the first "giant" adrenal myelolipoma diagnosed by computed tomography-guided FNA biopsy. The literature on adrenal myelolipomas sampled by FNA using imaging guidance is briefly reviewed.
