1. Define acute aortic syndrome with emphasis on intramural hematoma 2. Describe pathogenesis, natural progression, and potential complications of intramural hematoma 3. List cross-sectional imaging findings that impact management and prognosis 

1. Definition of acute aortic syndrome and its subtypes, including intramural hematoma and differences with penetrating aortic ulcer and incomplete dissection. 2. Controversies regarding pathogenesis of intramural hematoma (e.g. ruptured vasa vasorum versus microscopic intimal tear versus penetrating aortic ulcer). 3. Description of natural progression and possible complications of intramural hematoma including focal mural contrast enhancement (intramural blood pools and ulcerlike projections), progression to complete aortic dissection, and localized aortic dilatation or saccular aneurysm. 4. Cross-sectional findings which impact prognosis: initial size of intramural hematoma, initial maximum aortic diameter, Stanford type, initial presence or development of focal mural contrast enhancement, distinction of intramural blood pool from ulcerlike projection. 5. Outline current controversies regarding surgical, endovascular, and medical management of intramural hematoma.
