title: Chordoma mimicking the trigeminal schwannoma: a case report.
abstract: Intracranial chordomas are rare tumor arising from the remnants of embryologic notochord. Bony destruction and tumor calcification are their characters. Now we represent an extra-axial tumor with an unusual dumbbell shape in the right Meckel's cave and the appearance mimics the trigeminal schwannomas. However, the histopathological findings reveal a chordoma. Bony destruction in the right petrous bone and clivus provides a hint to make appropriate diagnosis.
