Abstract:
An aneurysm arising from the intracranial portion of the internal carotid artery(ICA) is usually found at the junction of the ophthalmic, superior hypophyseal, posterior communicating or anterior choroidal artery, or at the bifurcation of the internal carotid, but very rarely at the junction of the persistent trigeminal artery. We present a case of a 49-year-old man who presented with a massive subarachnoid hemorrhage, with large intracerebral hematoma due to rupture of the aneurysm originating from the distal portion of the internal carotid artery. During surgery, we found that the aneurysm was originated at the junction of the internal carotid artery and the artery arising from the distal to anterior choroidal artery. We considered this artery to be an anatomical variant of the uncal artery(UA) arising from the internal carotid artery.
