Fusiform aneurysm of the anterior communicating artery.
Fusiform aneurysms have often been reported on the internal carotid or vertebrobasilar arteries, but those solely involving the more distal segment of a cerebral artery seem to be exceptional. In a patient harboring two saccular cerebral aneurysms, angiography of the carotid arteries revealed a fusiform dilatation restricted to the anterior communicating artery. At autopsy, this dilatation proved to be a fusiform aneurysm.
