Media file 2: Contrast-enhanced computed tomography (CT) scan of the abdomen obtained during the nephrographic phase. This CT scan shows a well-defined, exophytic, solid mass from the midpole of the left kidney. The mass has an atypical appearance of an oncocytoma, is less attenuating than the renal parenchyma, and does not show a scar.
