Traumatic Aortic Intramural Hematoma
Imaging findings
CT chest in a trauma patient post-fall shows a non-displaced fracture of a thoracic vertebral body, with a very localized aortic wall thickening (intramural hematoma) and adjacent subtle paravertebral hematoma in close proximity to the vertebral injury.
Key takeaways
Blunt chest trauma can cause localized aortic injuries. When a thoracic vertebral fracture occurs, direct mechanical force or proximity to the bone fragments can lead to a localized aortic intramural hematoma or pseudoaneurysm. Careful evaluation of the aortic wall adjacent to spine fractures is critical.
