Persistent Primitive Hypoglossal Artery (PPHA) is a developmental anomaly of the brain superficial arterial circulation and is classified as a condition of carotid vertebrobasilar anastomosis persistence caused by lack of reabsorption of the vascular network running on the hindbrain surface between the 4th and 5th embryonic week. It has an incidence between 0.03 and 0.9%, it is the second most frequent seen per sistence of carotid-vertebrobasilar anastomoses after the trigeminal artery (TA), rep resenting 85% of all persistent vestigial arteries (0.1–0.6%). Here a case of Persistent Primitive Hypoglossal Artery (PPHA) is reported being detailed in its morphological and clinical aspects. The patient, a 55-year-old female patient with high cardiovascu lar risk without specific symptoms presents at radiological morphological examination with an anomalous bifurcation of the ICA which gives rise to the ICA itself, which ascends without collateral branches up to the carotid foramen in the cranial base, and to an accessory artery, which enters the hypoglossal canal on the contour of the great occipital foramen, as a PPHA. A comprehensive embryologic analysis of this anatomi cal variant is offered and clinical awareness on it raised in view of a more informed an effective realization of it in daily clinical practice.

Abstract
Persistent Primitive Hypoglossal Artery (PPHA) is a developmental anomaly of the brain superficial arterial circulation and is classified as a condition of carotid vertebrobasilar anastomosis persistence caused by lack of reabsorption of the vascular network running on the hindbrain surface between the 4th and 5th embryonic week. It has an incidence between 0.03 and 0.9%, it is the second most frequent seen per sistence of carotid-vertebrobasilar anastomoses after the trigeminal artery (TA), rep resenting 85% of all persistent vestigial arteries (0.1–0.6%). Here a case of Persistent Primitive Hypoglossal Artery (PPHA) is reported being detailed in its morphological and clinical aspects. The patient, a 55-year-old female patient with high cardiovascu lar risk without specific symptoms presents at radiological morphological examination with an anomalous bifurcation of the ICA which gives rise to the ICA itself, which ascends without collateral branches up to the carotid foramen in the cranial base, and to an accessory artery, which enters the hypoglossal canal on the contour of the great occipital foramen, as a PPHA. A comprehensive embryologic analysis of this anatomi cal variant is offered and clinical awareness on it raised in view of a more informed an effective realization of it in daily clinical practice.File | Dimensione | Formato | |
