CTICasesAortic Intramural Hematoma Evolving into Dissection
Imaging findings
Initial chest CT shows an ascending aortic intramural hematoma with mediastinal hemorrhage. Follow-up CT five weeks post-graft repair demonstrates a classic communicating aortic dissection in the distal arch and descending aorta.
Key takeaways
Intramural hematomas and communicating aortic dissections represent different phases or presentations of acute aortic syndrome. Intramural hematomas can rapidly progress or evolve into classic communicating dissections.
