title: Rhabdomyosarcoma arising in a pineal teratoma.
abstract: Pineal teratomas are relatively uncommon intracranial neoplasms. A rhabdomyosarcoma developed in a pineal teratoma in a 14-year-old boy and was rapidly fatal despite radiation therapy. This is the second reported case of a pineal teratoma giving rise to a rhabdomyosarcoma.
