Imaging findings
CT angiography shows a crescentic, non-enhancing thickening of the ascending and descending thoracic aortic walls measuring ~8mm in thickness, without a visible intimal tear or false lumen, representing a Stanford Type A intramural hematoma (IMH).
Key takeaways
Aortic intramural hematoma (IMH) is an acute aortic syndrome characterized by hemorrhage within the media without a detectable entry tear. While Type A IMH typically requires emergent surgery, select stable patients with thin hematomas (<10mm) and no complications may be managed medically under close imaging surveillance.
