A 61-year-old woman with primary adult type OGCT (Ia). There are oval, solid masses on right adnexal region (a, b) and right iliac fossa (c, d). Two lesions appears as similar signals with intermediate signal on both T1WI (a, c) and FS-T2WI (b, d) with intact capsule. On DWI image (e), the mass at the right iliac fossa shows relatively high signal (arrow) and low signal on the ADC map (f). The gross specimen reveals the yellow, solid mass with smooth capsule and a thin septa (g). Photomicrograph, hematoxylin and eosin stained section (× 40) shows the oval cells arrange closely with pleomorphic nuclei, prominent nucleoli and scanty cytoplasm. Note, the small vessels embed among the intercellular space (arrow head)
