A Serpiginous Pericallosal Anterior Cerebral Artery

The anterior cerebral artery (ACA) is a unique artery with many important variations with substantial clinical significance. Tortuous intracranial arteries usually occur in basilar, communicating, anterior, posterior cerebral arteries and in the white matter arterioles. This could happen for many reasons including but not limited to ageing, hypertension, patients with Moyamoya disease, congenital malformation, or increased flow associated with elastin degradation. While dolichoectasia of the ACA has been described even in children, to our knowledge, a serpiginous ACA without ectasia has not been reported, especially in the pediatric population.
