[Meningiomas. Histopathological aspects and recurrence].
The authors assessed 246 cases of meningiomas that were classified as typical, atypical, anaplastic and papillary, according to previously defined criteria. Among the criteria used to define non-typical tumours, brain invasion was predominant in 62.3%. Meningiomas were typical in 75.22%, atypical in 19.1%, anaplastic in 5.68% of the cases. There was recurrence in 3.78% of typical, 42.55% of atypical and 45.45% of anaplastic. The authors conclusion was that the criteria used to define typical and non-typical were adequate to predict a higher chance to tumour recurrences
