Extradural spinal meningioma: Revisiting a rare entity

Abstract

Spinal meningiomas are mostly intradural in location although at times these are associated with some extradural extensions. Purely extradural spinal meningiomas (EDSMs) are however, extremely rare and when present, may cause diagnostic dilemma preoperatively. Only seven cases of pure EDSM have been reported till date. In this paper, we describe two cases of EDSM affecting the cervical spine and present their clinical profiles, radiological findings, operative management, and follow-up data, along with a review of the literature.
