CTICasesStanford Type B Aortic Intramural Hematoma
Imaging findings
Non-contrast and contrast CT show a new, crescentic intramural hematoma along the descending thoracic aorta with displacement of the intimal calcifications inwardly in an anticoagulated patient presenting with acute back pain.
Key takeaways
Type B aortic intramural hematoma is an acute aortic syndrome. Inward displacement of pre-existing intimal calcifications is a key radiographic sign to differentiate intramural hematoma from simple atherosclerotic plaque.
