The correlation between cytogenetic and histopathological findings were analysed in 189 meningiomas. The tumors were classified according to increasing degrees of anaplasia. We observed normal karyotype or only monosomy 22 in grade 1 (benign) tumors, while in grade 3 (anaplastic) only 1.5% of karyotypes were normal. Grade 2 (atypical) and 3 (anaplastic) tumors showed complex structural abnormalities. Loss of chromosome 14 were only found in grade 3. In cases with complex structural rearrangements, fluorescence in situ hybridization technique (FISH) has been realized and permitted a best identification of abnormalities. In our series, five patients recurred. They presented chromosomal abnormalities. These complex karyotypes in recurrent meningiomas might indicate aggressive tumor characteristics. Our results indicate histolopathological and cytogenetics correlations might represent a prognostic factor in meningiomas.
