CTICasesPost-traumatic aortic pseudoaneurysm
Imaging findings
Chest radiograph and CT show a persistent, stable, focal outpouching at the aortic isthmus with a visible abnormal AP window interface, in a patient with a history of severe trauma two years prior.
Key takeaways
A chronic post-traumatic aortic pseudoaneurysm at the isthmus represents a healed or contained partial aortic tear. If stable on serial imaging over years, it may be managed conservatively with close surveillance.
