Overview
Meningioma may be classified according to the histological criteria of the WHO 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.[1][2]
Classification
- WHO has classified meningiomas into histo- and cytomorphological variants. Nine variants correspond to WHO grade I which are the benign classic meningiomas, two correspond to WHO grade II which are atypical meningiomas, and two in WHO grade III and are anaplastic malignant meningiomas.[3]
