Imaging findings
CT showed an abnormal vessel high in the neck, identified as the ascending aorta, forming a cervical aortic arch on the right. It then crossed behind the esophagus to descend on the left, creating a circumflex cervical aortic arch. Anomalies of the carotid arteries were also noted, with an early branching of the right common carotid.
Key takeaways
Cervical aortic arches are rare congenital anomalies, frequently associated with carotid artery anomalies. They can occur in isolation without other conal heart anomalies.
