Abstract

Meningioma is a common primary tumor of the central nervous system and one of the most encountered brain tumors. Although classic histopathologic features of meningioma are relatively common and make its diagnosis straightforward, certain variants possess unusual histologic features causing diagnostic challenges. We reported three cases of clear cell meningioma, microcytic meningioma, and angiomatous meningioma report, variants with potential deceptive morphologies, and discuss their distinguishing morphologic features.
