title: Extradural extension of glioblastoma multiforme into the oral cavity: case report.
abstract: A rare case of glioblastoma multiforme with oral extension is presented in a 41-year-old female. She underwent two surgical treatments and both radiotherapy and chemotherapy for the right temporoparietal glioblastoma multiforme. A follow-up computed tomographic scan and magnetic resonance imaging demonstrated destruction of the temporal base and extradural extension of the tumor into the orbital, nasal, and oral cavities. This is the first report of the oral extension of glioblastoma multiforme. The mechanism for the extradural extension is discussed.
