MRI of abdomen showing heterogeneous mass extending from the right suprarenal fossa and into the peritoneal cavity, measuring 10.2 cm x 10.5 cm x 8.5 cm (AP x TRV x SI). There are multiple large collections of high T2 signal consistent with cystic component degeneration.

An abdominal magnetic resonance imaging revealed a heterogeneous mass extending from the right suprarenal fossa and into the peritoneal cavity measuring 10.2 cm x 10.5 cm x 8.5 cm with multiple large collections consistent with cystic components, displacing the right kidney inferiorly (Figure 1).
Gross appearance showing irregular tan-white mass (a) and (b) cut section showing a heterogeneous surface with solid and cystic areas along with bony areas.

Cystic spaces were filled with clear fluid and lined with smooth tan/pink surface with focal areas of hemorrhage (Figure 2).

Intestinal and colonic mucosa were also present without any evidence of immature elements consistent with mature adrenal teratoma (Figure 3).
