Aortic intramural hematoma (IMH) is a pathologic process with a clinical presentation identical to aortic dissection and IMH is associated with significant morbidity and mortality. Radiologists must be familiar with the imaging appearances of IMH as CT plays a critical role in both diagnosis and patient management. The course of IMH is variable and the process may regress, remain stable or progress in extent and therefore imaging findings associated with a negative prognosis have been recognized and must be included in the formal radiology report. Potentially life-threatening complications and findings associated with IMH include hemopericardium and cardiac tamponade, co-existing aortic dissection, ulcer-like projection, intramural blood pool, extension of hematoma along the pulmonary or coronary arteries, and are identifiable with aortic protocol CT. The purpose of this pictorial review is to provide the reader with an image-based review of the diagnostic criteria, related complications and associated critical prognostic features in patients presenting with aortic IMH.
