Deep Sylvian Meningioma: Case Report

We report a case of deep sylvian meningioma without any dural attachment in a 36-year-old man. The patient presented with generalized tonic clonic seizure. Magnetic resonance images revealed a well enhancing round mass in the superior aspect of the left insular region. Surgical resection confirmed transitional type of meningioma. Gamma knife radiosurgery was undergone to control the tumor growth after partial resection. So far, supratentorial meningioma without any dural attachment has been rarely reported.
