- Ulceration of an atheromatous plaque that
- extends deeply
- through the intima and
- into the aortic media
- may result in localized medial dissection
- may extend into the adventitia to form a pseudoaneurysm
- and is usually associated with a variable amount of hematoma
- distinguishing between
- aneurysm
- dissection
- ulceration is sometimes
- CT
-
- lesion progresses to the media
-
-
May focally dissect
Dissection could be progressive
- Advance to the adventitia and form an aneurysm or pseudoaneurysm
- Rupture
-
2nd Case
- Magnetic resonance imaging
- superior to conventional CT in
- differentiating
- acute intramural hematoma from
- atherosclerotic plaque and chronic intraluminal thrombus
