Abstract
Meningiomas receive their major blood supply from meningeal vessels, either from the external carotid artery or meningeal branches of the internal carotid artery, depending on the location of the tumor. The dura about the base of the skull is supplied principally by branches of the internal carotid artery. These vessels hypertrophy in pathologic states. Selective internal and external carotid artery injections are necessary to definitely determine the origin of tumor vessels and for the fine roentgen delineation essential to accurate diagnosis and histologic correlation. The technique of selective carotid angiography by catheterization is described and examples of meningioma demonstrated by this method are illustrated.
