Other findings in this case

  • deformed chest with increased AP diameter and associated scoliosis

Case Discussion

Bovine arch is one of the more common forms of aortic arch variations we encounter in our daily practice. They are rarely symptomatic. Detection of one vascular variant should prompt detailed evaluation of others in the examined study.
