Instead, a summary of the latest World Health Organization 2000 classification of meningiomas is presented: grade I (low risk of recurrence and aggressive growth) includes meningothelial, fibrous (fibroblastic), transitional (mixed), psammomatous, angiomatous, microcystic, secretory, lymphoplasmacyte-rich and metaplastic meningiomas; grade II (greater likelihood of recurrence and/or aggressive behavior) includes atypical, clear cell and chor-doid meningiomas; grade III includes rhabdoid, papillary and anaplastic (malignant) menin-giomas, as well as any subtype named above that has a high proliferation index and/or brain invasion.
