Transdural Spread of Glioblastoma through the Foramen Ovale with Presentation as a Masticator Space Mass

Abstract

SUMMARY: Direct extension of a glioblastoma through the dura at the skull base is an uncommon occurrence. We report an unusual case of recurrent glioblastoma that spread transdurally through the foramen ovale and presented primarily as a masticator space mass. There was mandibular denervation and a relative paucity of intracranial disease.
