Abstract
eningiomas are extra-axial slow growing tumours originating from non-neuroepithelial progenitor cells, the arachnoid cap cells. Meningioma is the most benign tumor of the brain but recurrence is the issue. Although meningiomas generally grow slowly, some recur even after radical resection. Recurrences of meningiomas are attributed not only to incomplete removal but also to histologic aggressiveness. Even benign meningiomas may invade adjacent duraor bone beyond the macroscopic border, and microscopic slowly growing remnants of the tumor cells may be inadvertently left after surgery. This study included 12 patient with recurrent intracranial meningioma, presenting to neurosurgical department of Menoufia University from Jan 2008 – Jan 2010.
