case_images: Computerized tomography (CT) of the abdomen revealed a solid heterogeneous mass lesion measuring 11.2 cm x 8 cm x 12 cm, consistent with retroperitoneal hematoma [Figure 1a]. Ultrasonography (USG)-guided aspiration of the mass was performed and the smears were hypercellular with small, overlapping cell clusters and cells in a microfollicular pattern [Figure 1b]. Histologically the neoplasm was composed of small round to oval neoplastic cells with predominantly microfollicular [Figure 1c], diffuse, and watered-silk patterns. The tumor was positive for inhibin [Figure 1d] and negative for EMA.
