Persistent trigeminal artery: rare cause of ischemic stroke in young people

A young girl, 17-years-old, history of drug addiction, followed for thrombophilia with a right hemiplegia due to a left superficial sylvian infarction for 6 months, hospitalized for etiological exploration. Cerebral magnetic resonance imaging showed a sequela of left frontal ischemia due to occlusion of the superficial branches of the left middle cerebral artery (Figure. 1), with the presence of an artery connecting the basilar trunk and the left internal carotid artery, also called the persistent trigeminal artery (Figure. 2).
