Ductus diverticulum

Case contributed by Dr Alan Jossimar Zavala Vargas


Acute chest pain and respiratory distress. Discard pulmonary embolism.

Patient Data

Age: 50 years
Gender: Female

Contrast CT shows an out pouching of the thoracic aorta at the anteromedial aspect of the isthmus, where the ligamentum arteriosum attaches. No filling defect to suggest a pulmonary embolism (the reason why the study was requested).

Case Discussion

Ductus diverticulum is typically an incidental finding.  Most patients are asymptomatic. It presents in 9 - 26% of adults. 

The radiologist must recognize and be very careful to differentiate pseudoaneurysm from the ductus diverticulum if there is a history of trauma.
