There was male pattern of hair distribution [Figure 1].
Arterial phase axial multidetector computed tomography (MDCT) scan of the abdomen shows a hypervascular heterogeneously enhancing mass with radially arranged vessels (arrows) in the right adrenal region.

Arterial phase scan (acquired at 30 s) showed a tangle of serpiginous, thin intratumoral vessels throughout the mass except in the central stellate nonenhancing area [Figure 2]. The periphery of the mass was supplied by dilated, thick, tortuous vessels arising from phrenic and renal vessels [Figure 2].
Volume rendered image of the abdomen depicts the hypervascular mass, in the right adrenal area, giving a can-of-worms appearance (arrows).

These vessels gave a can-of-worms like appearance on volume rendered images [Figure 3].
Axial multidetector computed tomography scan scan of the abdomen in the portal venous phase shows the mass in right adrenal region with early wash-out of contrast and a central nonenhancing area (arrow).

In the venous phase scan (acquired at 60 s), the mass showed homogenous enhancement except for the central nonenhancing area [Figure 4].
