Atypical meningioma: a clinicopathological analysis. Neurology India. 2000 Dec; 48(4): 338-42http://imsear.searo.who.int/handle/123456789/119978In this retrospective study, 382 operated cases of meningiomas were reviewed. 32 cases (8.3%) were histopathologically classified as atypical meningioma. The anatomical locations and histological features in all the thirty-two cases were correlated with their recurrence rates and biological behaviour. The overall recurrence rate for atypical meningioma within two years was 28% as compared to 9.3% in benign meningiomas. It is being emphasized that an accurate histopathological interpretation of atypical meningioma is essential for predicting the recurrence, biological behavior as well as post-operative management modalities.engAdultAgedFemaleFollow-Up StudiesHumansMaleMeningeal Neoplasms --pathologyMeningioma --pathologyMiddle AgedNecrosisNeoplasm Recurrence, LocalRetrospective StudiesJournal Article
