title: [Distal intracranial arterial aneurysms. Apropos of a case of giant aneurysm of the right angular gyrus artery].
abstract: A 57 year old man presented with a giant, fusiform, partially thrombosed aneurysm, located distally to the right angular gyrus artery, and revealed by a subarachnoïd hemorrhage. There was no history of head trauma, endocarditis or systemic infection, and physical examination was normal. The treatment consisted in simple trapping of the aneurysm, responsible for a transient ischemic parietal syndrome. After a short review of the pathogenesis of peripheral aneurysm of the C.N.S., and previously reported cases of distally located aneurysms of the middle cerebral artery, only one similar case was found concerning a posterior temporal artery aneurysm involving to a giant serpentine aneurysm. The case presented is believed to be a segmentary form of cerebral arterial dolicho ectasia; relations between arterial ectasia or fusiform aneurysms and serpentine aneurysms are discussed.
