Dipanker Singh Mankotia et al. Asian J Neurosurg. 2018 Jan-Mar.

Abstract

Intradiploic meningioma is a rare subset of meningioma accounting for 1% of all cases. Authors report a rare case of giant sphenotemporal intradiploic meningioma with orbital extension in a 27-year-old female. It was managed successfully with complete surgical excision and bony reconstruction using autologous split thickness bone graft.

Keywords: Intradiploic; intraosseous; meningioma; primary extradural meningioma; sphenotemporal.
