Abstract
PURPOSE: Variance of aortic arch branches are clinically significant as they are encountered in multiple endovascular treatments. The knowledge of different variants is crucial to perform successful vascular interventions. METHODS: We report a novel anatomical variant of aortic arch found on contrast-enhanced computed tomography scan during a workup of cervical lymphadenopathy. RESULTS: The CT neck revealed a bovine aortic arch with an aberrant origin of bilateral vertebral arteries from the aortic arch. The right vertebral artery arose between the bovine trunk and the left subclavian artery, while the left vertebral artery was present distal to the left subclavian artery. CONCLUSION: This article sheds light on the potential clinical significance of these various types of aortic arch branches. Knowing the exact type of variant is particularly important in patient undergoing management involving carotid and surrounding vessels.
