Tectal glioblastoma

brain stem gliomas are a heterogeneous group of neoplasms arising mostly in paediatric patients. tectal plate gliomas represent a particular type of brain stem tumours usually with a benign, indolent clinical course, presenting with signs of raised intracranial hipertension due to supra-tentorialhydrocephalous caused by aqueductal stenosis. seldom high-grade lesions arise in this location with tremendous therapeutic implications. when a malignant tumour is clinically and radiographically suspected a biopsy should be performed to obtain histhological confirmation. treatment is then planned in a case-by-case basis. we present the case of a glioblastoma of the tectal plate in a 22 years-old woman operated upon by a supracerebellar-infratentorial approach.
