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 15 histo- and cytomorphological variants. Nine variants correspond to WHO grade I which are the benign classic meningiomas, three correspond to WHO grade II which are atypical meningiomas, the other three are in WHO grade III and are anaplastic malignant meningiomas.[3]
- The table below lists the subtypes of meningioma according to the WHO grades:[3]
| WHO grade | Subtypes |
|---|---|
|
Benign classic meningioma |
|
|
Atypical meningioma |
|
|
Anaplastic malignant meningioma |
