Among 98 surgically-treated intracranial meningiomas, 12 (% 12.2) patients with atypical and anaplastic meningiomas are reviewed. All were operated between 1983-1994. Out of 12 patients, 7 (58%) had malignant meningioma and 5 (42%) showed atypical features histopathologically. Tumours in eight patients were recurrences, most in grade 3 resected patients, showing the importance of the grade of the surgical resection. Cases were reviewed according to their clinical, histopathological and radiological findings and survivals in the light of the literature. Keywords : Atypical and malignant, meningiomas, radiation, recurrence
