Cases of Ovarian Tumor

Cases of Ovarian Cystadenoma

CT of ovarian cystadenoma
Axial, coronal and sagittal images from a CT with contrast of the abdomen shows a large cystic mass with thin separations on the right side of the abdomen above the bladder. The uterus and left ovary were unremarkable.

Cases of Ovarian Dysgerminoma

US and CT of ovarian dysgerminoma with torsion
Transverse and sagittal US of the pelvis (above) shows an echogenic and inhomgenous solid mass superior to the bladder. Neither ovary could be visualized. Axial CT with contrast of the abdomen shows a solid non-enhancing midline mass. The mass was found to be tossed in the operating room.
