An Adrenal Myelolipoma With Hemorrhage

Abstract

An 80-year-old man with a history of abdominal aortic aneurysm presented after a large left adrenal mass was found on surveillance ultrasonography. A subsequent abdominal and pelvic computed tomography (CT) scan revealed a 15-cm heterogeneous, round mass with a small internal fat component (Fig. 1A) with evidence of focal active extravasation of contrast within the mass consistent with active hemorrhage (Fig. 1B). On his CT 4 years prior, the adrenal lesion measured 4.9 cm and had areas of macroscopic fat and punctate calcifications consistent with a myelolipoma.
