Concomitant occurrence of acute aortic dissection and atherosclerotic aneurysm is rare. In such a circumstance, rupture of the existing aneurysm is the more likely scenario. In general, atherosclerotic plaque frequently serves to terminate the dissection process. A 65-year-old man with an abdominal aortic aneurysm was admitted due to severe back pain. Emergency CT showed acute aortic dissection (Stanford B) with a partially thrombosed pseudo-lumen and fusiform abdominal aortic aneurysm. Hemolysis occurred due to compression of the true lumen by the thrombosed pseudo-lumen. Emergency abdominal aortic graft replacement was performed successfully.
