A Case of Mixed Germ Cell Tumor in the Third and Lateral Ventricle

ABSTRACT

The authors report a case of mixed germ cell tumor arising at the third ventricle and extending to the lateral ventricle in a sixteen-year-old male who presented with headache, nausea, vomiting and polydipsia. Magnetic resonance imaging of the brain demonstrated a lobulated mass in the third and left lateral ventricle. For surgery, the anterior interhemispheric transcallosal approach was used, and on histologic examination three concurrent histologic components were found germinoma, embryonal carcinoma, and endodermal sinus tumor.
