Image A: axial CT imaging with IV and PO contrast showing heterogeneously-enhancing 4 cm right adrenal mass (red arrow) with 2 cm central cystic component. Image B: axial MR imaging with IV and PO contrast of right adrenal mass (red arrow) demonstrating heterogeneous features and avid enhancement of cystic components.

A large, heterogeneous mass was visualized overlying the right kidney (Fig. 2, Image A). On removal, the specimen measured approximately 8 cm in diameter (Fig. 2, Image B).
(A): Light micrograph of hematoxylin & eosin stained section (100 X H&E). Zellballen (small nests or alveolar pattern), trabecular or solid patterns of polygonal/spindle shaped cells in rich vascular network. (B): Immuno-histochemical staining with anti-chromogranin A and anti-synaptophysin antibodies. Residual adrenal gland cortex and surrounding benign fat.
