From: Pure dysgerminoma of the ovary: CT and MRI features with pathological correlation in 13 tumors
A 23-year-old woman with dysgerminoma in the right ovary. a Coronal T2- weighted image displays a large multilobulated heterogeneous mass with thin, hypointense septa (arrows). b The mass shows high signal intensity with the septa as low signal intensity (arrows) on DW imaging (b = 1000 s/mm2). c The mass has a moderate contrast enhancement on T1-weighted images. The septa are enhanced obviously (arrows). d The photomicrograph (H&E, 100×) shows tumor cells arranged in islands separated by fibrous septa (*). e Higher power image (H&E, 400×) shows polygonal tumor cells with distinct cell borders
