Intraosseous schwannoma in the clivus mimicking chordoma treated with endoscopic endonasal surgery: A case report.

ABSTRACT:

Background

Intraosseous schwannomas are extremely rare and they have not yet been reported to occur in the clivus. We report a schwannoma in the clivus mimicking chordoma and review intraosseous schwannomas of the skull.
