Case report: adrenal myelolipoma--rationale for a noninvasive diagnosis.

Myelolipomas are nonfunctioning, benign tumors of the adrenal gland composed of fat and normal bone marrow elements in varying proportions. Although rare, they should be included in the differential diagnosis of the incidentally discovered adrenal mass. The authors describe a patient with a myelolipoma diagnosed by characteristic radiological findings in whom the use of invasive procedures or surgical exploration was unnecessary.
