SUPRASELLAR EMBRYONAL CARCINOMA WHICH DEVELOPED 10 YEARS AFTER LOCAL RADIATION-THERAPY FOR PINEAL GERMINOMA

We recently encountered a case of suprasellar embryonal carcinoma whic h developed 10 years after local radiation therapy for pineal germinom a. This 29-year-old male was admitted because of abnormal behavior, di sturbed consciousness, and increased intracranial pressure. Computed t omography and magnetic resonance imaging disclosed a tumor spreading f rom the suprasellar region to the third ventricle and the anterior hor n of the left lateral ventricle, accompanied by fresh hemorrhage withi n the tumor. He underwent subtotal removal of the tumor, followed by c hemotherapy with cisplatin and etoposide. The tumor was histologically rated as embryonal carcinoma with differentiation into yolk sac tumor and choriocarcinoma.
