Resumos
Os autores realizaram a avaliação de 246 casos de meningeomas que foram classificados como típico, atípico, anaplásico e papilar segundo critérios previamente definidos. Entre os critérios utilizados para definição de tumores não típicos, a invasão do sistema nervoso central predominou com 62,3% dos casos. Os meningeomas foram típicos em 75,22% dos casos, atípicos em 19,1%, anaplásicos em 5,68%. Houve recidiva em 3,78% dos meningeomas típicos, em 42,55% dos atípicos e 45,45% dos anaplásicos. Os autores concluem que os critérios utilizados para definição de típicos e não típicos foram adequados para predizer maior chance de recidiva tumoral.

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 recurrence.

ABSTRACT
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 recurrence.
Key words: meningiomas, histopathology, recurrence.
