CTICasesDouble Aortic Arch
Imaging findings
Radiographs showed indentation on both sides of the trachea and a fullness in the right paratracheal space. CT confirmed a symmetric double aortic arch causing vascular ring symptoms.
Key takeaways
Vascular rings, though rare (approximately 1 in 10,000), should be considered in patients with persistent airway or swallowing symptoms; look for tracheal indentation on multiple views.
