title: Supernumerary fronto-orbital arteries arising from contralateral anterior cerebral artery associated with partially duplicated anterior communicating artery - case study and literature review.
abstract: The anatomical variations of the fronto-orbital artery are uncommon and rarely described in literature. During the dissection of a 64-year-old female formalized brain, we discovered a particular congenital abnormality regarding the arterial supply of the right fronto-orbital gyrus. We identified three arterial sources: a low caliber ipsilateral fronto-orbital artery that arises from the A2 segment of the right anterior cerebral artery and ends in the posterior part of the fronto-orbital gyrus, a large aberrant contralateral fronto-orbital artery that arises from the A2 segment of the left anterior cerebral artery, supplying most of the right fronto-orbital gyrus and a small accessory branch of the left anterior cerebral artery passing towards the contralateral fronto-orbital gyrus. These abnormalities are associated with a partially duplicated anterior communicating artery. This case shows a unique pattern of congenital brain vascular abnormalities that may have clinical and surgical implications.
