Adrenal myelolipoma: comparison of diagnostic imaging and pathological findings.

Myelolipoma of the adrenal gland is a rare, benign, nonfunctioning lesion consisting of fat and bone marrow elements in varying proportions. This tumor is commonly asymptomatic and usually discovered during various diagnostic imaging examinations performed for unrelated diseases. If a primary malignant or metastatic adrenal tumor cannot be excluded, ultrasound- or computed tomography-guided needle biopsy of the tumor is necessary. We report a case of adrenal myelolipoma associated with advanced gastric carcinoma and compare the diagnostic imaging findings with the pathological findings of the adrenal myelolipoma.
