From: Pure dysgerminoma of the ovary: CT and MRI features with pathological correlation in 13 tumors
A 21-year-old woman with bilateral ovarian dysgerminomas. a Axial T2-weighted with fat suppression image displays a large heterogeneous solid mass. There are massive void vessels in amorphous hyperintense septa. b The mass has a moderate contrast enhancement on T1-weighted image. The septa are enhanced slightly and the dilated vessels are enhanced markedly. c, d Pre- and post -contrast CT scan show a heterogeneous mass with prominent intratumoral vessels. e Sagittal MPR displays the bilateral lesions (R and L). f VR demonstrates the thickened ovarian vein (arrows) and the extending intratumoral reticular vessels. g The photomicrograph (H&E, 100×) shows the stromal septa in the upper were edematous and amorphous with massive dilated blood vessels (*)
