Aneurysm of the Pericallosal Artery Caused by Closed Cranial Trauma

Abstract

S EVERAL instances of traumatic intracranial arterial aneurysm after penetrating injury or fracture adjacent to the internal carotid or middle meningeal arteries have been reported. ' The development within a few days or weeks after closed cranial t rauma of an aneurysm on an artery shown to be free of aneurysmal dilatation immediately following the injury has rarely been documented, and must certainly be an unusual occurrence. We have recently performed serial carotid arteriograms on such a patient and have observed the development of an apparently t raumat ic aneurysm of the right pericallosal artery.
