Traumatic aortic intramural hematoma

Aortic intramural hematoma (IMH) is an entity of acute aortic syndrome. In IMH, haemorrhage occurs within the aortic wall in the absence of intimal disruption. IMH may occur spontaneously, develop from penetrating atherosclerotic ulcer, or be secondary to the external or internal aortic injuries. IMH can regress spontaneously or evolve into aortic dissection. Hematoma of the descending aorta also has a better prognosis than dissecting hematoma. Subrenal aorta IMH localisation is rare. We report a case of IMH of the subrenal aorta evolving in non-specific abdominal pain, after a massage, and expose its radiological particularities.
