Objective: The current classification of meningioma is based on the mitotic count, brain invasion and atypical histological changes. We re-evaluated the cases of meningioma to make accurate grading and to investigate the effects of morphological parameters and their relationship with each other. We discussed the counting method of mitotic activity. We tried to develop a novel method to determine the most accurate grade.
