title: A fusiform aneurysm of a persistent trigeminal artery variant: case report and literature review.
abstract: A 48-year-old man suffered from spontaneous subarachnoid hemorrhage. Emergent right internal carotid angiography showed the presence of a persistent trigeminal artery (PTA) variant with a fusiform aneurysm on its proximal segment where it branched from the internal carotid artery. This artery supplied the territory of the anterior inferior cerebellar artery. After consideration of the adequacy of the cerebellar circulation without this anomalous artery, intraluminal occlusion of the aneurysm together with the PTA variant was performed using detachable coils. The patient recovered uneventfully without any neurologic deficits.
