Presentation
MVA rollover at 100km/hr - complaining of chest and back pain.
Patient Data
Focal bulge at the anteromedial aspect of the aorta has smooth contours and along with the absence of mediastinal hematoma is in keeping with a ductus diverticulum. Air embolus noted within the pulmonary trunk. No pleural fluid collection. No rib, sternal or scapula fractures are seen.
Case Discussion
A ductus diverticulum is a normal variant representing a developmental outpouching of the thoracic aorta. It is a key differential diagnosis for thoracic aorta traumatic injuries (e.g. pseudoaneurysm), which commonly occur at the same location.
