Acute aortic intimal tear without a mobile flap mimicking an intramural hematoma.

Several variants of aortic pathology must be considered in the differential diagnosis of the patient presenting with an acute aortic syndrome. In addition to aortic dissection, such entities include intramural hematoma, penetrating aortic ulcer, and localized intimal tear without dissection. These lesions, which lack a mobile intimal flap, may be difficult to correctly identify by transesophageal echocardiography or other imaging modalities. We present a case of an acute aortic syndrome with unusual features on transesophageal echocardiography.
