Result: The percentage of hyperdiploid cells, DNA Index and proliferative index were statistically higher in the vascular and the syncytial subtypes of meningioma than those in the fibrous and mixed subtypes, Also those in the severe edema group were higher than those in the moderate, mild and without peritumoral edema groups. The DNA hyperdiploidy were mostly found in the group of giant size tumor, DI and PI in the recurrent menigioma group were significantly higher than those in the nonrecurrent group.
