Meningioma is the most common type of tumor that forms in the head and may affect the brain. Falcine meningiomas arise from the falx cerebri and make up approximately 5% to 9% of all intracranial meningiomas. 1-2 Falcine meningiomas differ from parasagittal meningiomas in that parasagittal tumors originate from the dura mater enclosing the superior sagittal sinus and are up to 5 . Parafalcine meningioma is a common meningioma located in the cerebral longitudinal fissure, originating from the cerebral falx, with the third highest morbidity among all the meningiomas, accounting for approximately 11%-14% deaths, ranking only second to the cerebral convexity meningioma and parasagittal meningioma (the term parasagittal meningioma applies to those tumors .
