Overview

Meningioma may be classified according to WHO histological criteria into 3 groups: benign classic meningioma (WHO grade 1), atypical meningioma (WHO grade 2), and anaplastic malignant meningioma (WHO grade 3). Meningioma may also be classified according to the tumor location into 2 main subtypes: intradural and extradural meningioma.

Classification

Meningioma may be classified according to WHO histological criteria into 3 groups: benign classic meningioma (WHO grade 1), atypical meningioma (WHO grade 2), and anaplastic malignant meningioma (WHO grade 3).


WHO grade	Subtypes

Benign classic meningioma (WHO grade 1)	Meningeothelial, fibroblastic, transitional, psammomatous, angiomatous, microcytsic, secretory, lymphoplasmacyte-rich, metaplastic
Atypical meningioma (WHO grade 2)	Chordoid, clear cell
Anaplastic malignant meningioma (WHO grade 3)	Rhabdoid, papillary
