Duplicate origin of the anterior cerebral artery diagnosed by magnetic resonance angiography: a case report

Surg Radiol Anat. 2016 Dec;38(10):1239-1241. doi: 10.1007/s00276-016-1688-8. Epub 2016 May 5.

Abstract

An anterior cerebral artery (ACA) of duplicate origin results from the fusion of two arteries that arise from the terminal segment of the internal carotid artery (ICA) to form a ring. This variation is extremely rare and differs from proximal ACA fenestration, supraclinoid fenestration of the ICA, and duplicate origin of the middle cerebral artery. We report a case diagnosed incidentally by magnetic resonance angiography.

Keywords: Anterior cerebral artery; Arterial ring; Duplicate origin; Fenestration; Magnetic resonance angiography.
