VIDEO: Rethinking "Mural Thickening:" Vasculitis or Aortic Dissection?

Objective: The objective of this video article is to provide education about the similarities and differences between vasculitis and rare, acute aortic pathologic findings so that an appropriate diagnosis can be made in a timely manner, especially for patients with life-threatening aortic pathologic findings.

Conclusion: Although they are rare, acute aortic pathologic findings, such as aortic dissection and intramural hematoma, can have radiographic characteristics similar to those of vasculitis, which can make it challenging to discern between these vastly different diagnoses without the use of properly timed imaging studies.
