title: Rhabdoid tumor: an unusual pediatric brain tumor.
abstract: Rhabdoid tumors of the brain are rare with an invariable dismal prognosis despite treatment. This is the case of a 3 year old boy who presented lethargy, somnolence, nausea, vomiting, and headaches one week prior to hospitalization. A posterior fossa tumor with hydrocephalus was noted on a head computed tomography (CT) scan. A ventriculoperitoneal shunt was placed with subsequent gross total tumor resection. Pathology findings were those of a rhabdoid tumor. The histopathology, immunohistochemistry and ultrastructure of this unusual pediatric cerebral neoplasia is discussed.
