CTICasesIntramural Hematoma with Progression to Ulcer-Like Projections
Imaging findings
Serial CTA scans of the thoracic aorta show an acute Type B intramural hematoma (IMH) that progressed over two months to develop multiple small intramural blood pools and a wider-mouthed, high-risk ulcer-like projection.
Key takeaways
Intramural hematomas of the aorta are part of the acute aortic syndrome spectrum. Development of ulcer-like projections (ULPs) with a wide connection to the lumen indicates focal intima disruption and carries a high risk of progression, dissection, or rupture.
