Cerebellar glioblastoma in the elderly--case report.

Cerebellar glioblastoma in the elderly is rare. Only 33 cases have been reported in the literature. We report on a 65-year-old male patient with cerebellar glioblastoma. Computed tomography scan revealed a posterior fossa tumor of 34 x 33 x 52 mm in size, with hydrocephalus. The patient presented with posterior fossa symptoms, ataxia, nausea and vomiting. He deteriorated rapidly and ventricular drainage was performed. When the patient's condition improved, suboccipital median craniectomy was performed and the tumor was removed. Postoperative treatment included radiotherapy and temozolomide chemotherapy.
