Post-Traumatic Bronchial Artery Pseudoaneurysm: A Case Report.

A 34-year-old woman with a history of Turner syndrome presented to the emergency department after a high-speed motor vehicle collision. Computed tomography (CT) of the thoracic spine demonstrated an unstable inferior endplate fracture of T7 with bilateral laminar fractures. Computed tomography angiography (CTA) of the chest and magnetic resonance angiography (MRA) of the aorta demonstrated a 6-mm focal outpouching of contrast along the right aspect of the descending thoracic aorta, concerning for an unruptured bronchial artery pseudoartery aneurysm. Digital subtraction angiography (DSA) confirmed a pseudoaneurysm arising from the origin of the right bronchial artery, which was successfully treated with coil embolization.
