Primary intracranial endodermal sinus tumor. Case report.

Endodermal sinus tumor (yolk sac carcinoma), a germinal neoplasm, is rarely primary in the cranial cavity. The authors add a third case with the tumor located in the anterior third ventricular (suprasellar) region to the literature. Seventeen previously reported intracranial cases, mostly in the pineal region, are briefly reviewed.
