Abstract: Meningiomas, are most common extra-axial intracranial tumours, mesodermal or meningeal origin, and the most common benign tumour that rarely invades substance of the brain, thus presenting the potential for cure after surgery. The prevalence varies from 2.3/1 lakh people during their life span to 5.5/1 lakh population if autopsy data were included.1
Cushing and Eisenhardt defined the parasagittal meningioma as one that fills the parasagittal angle, with no brain tissue between the tumour and the superior sagittal sinus (SSS).2 Cushing (1922),in his series of 751 intracranial tumours, reported parasagittal meningioma accounting for 32% of total.3Subsequent large series have shown that parasagittal meningioma.......
