Abstract

We have recently experienced a case of ependymoblastoma arising in the posterior fossa. 8 years old Korean boy suffered from headache, vomiting, diplopia and ataxic gait since 4 months prior to admission revealed drowsy mental state papilledema of both eyes, left abducens nerve paralysis, mild cerebellar syndrome in the neurologic examination. The radiological findings of skull revealed increased intracranial pressure and brain CT scan showed calcified round high density mass in the posterior fossa. After 3 weeks of V-P shunt operation, relatively well demarcated grayish-pink mass between the vermis of cerebellum and right cerebellar hemisphere was removed. The histological finding had a pattern of solid cord aroused thin walled blood vessel and typical ependymal rosette. The patient died at 6th postoperative day due to brain stem swelling.
