Pure Intrasellar Meningioma Mimicking Pituitary Macroadenoma: Magnetic Resonance Imaging and Review of the Literature

Abstract

Intrasellar meningioma originating from the sellar floor is extremely rare and is often indistinguishable from pituitary macroadenoma, both clinically and radiologically. Here, we report a case involving a 68-year-old patient with intrasellar meningioma possibly originating from the sellar floor and present a brief review of all previous cases reported in the English literature.
