The persistent trigeminal artery (PTA) is a rare vascular anomaly which represents a persistent communication between the internal carotid artery and vertebrobasilar system. This anastomosis is important because it provides the main source of blood supply during the development of the embryonic brain in its most critical stage. The diagnosis, in the majority of cases, concerns an incidental finding. The 25% of the persistent trigeminal arteries are linked to some vascular brain diseases, especially with intracranial aneurysms, and neurophthalmologic involvement is not frequent. This case reports a male patient who developed proptosis and a complete ophthalmoparesis of the third cranial nerve with an anatomical variant of the normality consisting of a PTA detected by the magnetic resonance imaging.

Keywords: Oculomotor nerve. Proptosis. Angiography. Diplopia. Ophthalmoplegia.
