Pediatric Ovarian Tumor

  • Etiology:
    — epithelial cell tumors (70%) – serous / mucinous
    — germ cell tumors (20%) – teratoma / dysgerminoma / endometrial sinus tumor / choriocarcinoma
    — sex cord tumors (10%) – granulosa-theca tumor / Sertoli-Leydig cell tumor
    — others – metastases / lymphoma /leukemia
  • Complications: peritoneal metastasis

Radiology Cases of Ovarian Tumor

Radiology 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.

Radiology 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.

Pathology Cases of Ovarian Tumor

Pathology Cases of Ovarian Dysgerminoma

Surgical image of ovarian dysgerminoma causing ovarian torsion
Surgical image (above) shows a mass arising from the left ovary. Surgical image (below) shows the left adnexal pedicle to be twisted in the center of the image. The mass and the left ovary and the fallopian tube were found to be torsed.
