Primary glioblastoma multiforme of the pineal region with leptomeningeal metastases: A case report

Abstract

The incidence of primary intracranial glioblastoma multiforme originating in the pineal region is exceedingly rare. Diffuse leptomeningeal involvement, including spinal subarachnoid metastases, by a primary glioblastoma multiforme of the pineal region has not been reported. A report of a case of primary glioblastoma multiforme of the pineal region accompanied by diffuse leptomeningeal and nodular spinal subarachnoid metastases is presented. Extensive evaluation of the complete neuraxis, including histologic examination, in all cases of primary pineal neoplasm appears to be of both diagnostic and therapeutic value.
