Imaging features of intramural hematoma of the aorta

Int J Cardiovasc Imaging. 2010 Jan;26(1):65-76. doi: 10.1007/s10554-009-9504-8. Epub 2009 Sep 24.


Intramural hematoma (IMH) is defined as localized hemorrhage within the aortic wall and is included in the acute aortic syndrome spectrum with aortic dissection and penetrating aortic ulcer. The mortality from IMH is similar to classic aortic dissection (21%). 16% of patients with IMH will evolve to classic aortic dissection over time. Despite this confusion exists regarding the precise definitions and radiologic features of IMH versus penetrating ulcers with mural thrombus and overt aortic dissection.
