This document discusses the vascular supply and blood vessel encasement/involvement of different types of meningiomas in 3 locations: anterior skull base, middle skull base, and posterior skull base. It lists the specific arteries that supply each type of meningioma and the blood vessels that can become encased, such as the internal carotid artery in anterior skull base meningiomas. The document is a reference for neurosurgeons regarding the angiographic features and vascular involvement of meningiomas in different skull base regions.
