Primary intracranial yolk sac tumor usually arises in the pineal or suprasellar area and shows poor prognosis. Several children with primary yolk sac tumor in the cerebellum have been reported in the literature, and none of these survived beyond 30 months. We report a case of primary yolk sac tumor in the cerebellum showing longer survival with intensive multimodal combined therapy using surgery, preirradiation chemotherapy, and irradiation.
