As with [[intracranial meningioma]]s in other regions, [[skull base]] meningiomas demonstrate a [[female]] predominance, with a female-to-[[male]] ratio as high as 3:1. Approximately 15% of meningiomas grow along the [[sphenoid ridge]], with 10% developing in the [[posterior cranial fossa]] and 5% in the [[olfactory groove]]. Meningiomas of the floor of the [[middle fossa]] are uncommon and tend to grow quite large before diagnosis. Skull-base meningiomas are characterized by other recurrent mutations, including [[AKT]]1, [[SMO]], [[KLF4]], [[TRAF7]] and [[POLR2A]]. skull_base_meningioma_epidemiology.txt Last modified: 2024/06/07 02:48by 127.0.0.1
