The persistent trigeminal artery (PTA) is the most common and most cephalic embryological vascular remnant that persist in the adulthood. It is located between the internal carotid artery and the basilar artery. It is recognized on 0.1%–0.6% of cerebral angiography. In most cases is an incidental finding, but may be associate with others cerebrovascular malformations, including arteriovenous malformations, aneurysms, and carotid-cavernous fistulas, which cerebral aneurysms are the most common. We describe an extremely rare case of unruptured aneurysm in the PTA trunk revealed by angiotomography successfully treated with endovascular embolization. A proper diagnose prior to any surgical or radiological intervention is crucial to prevent possible complications.
