[Spontaneous regression of a false aneurysm of the ascending aorta following surgery for dissection]

We report the case of a 50-year-old man admitted to hospital for a type A aortic dissection. After conventional surgical repair, he was asymptomatic and underwent computed tomography imaging at 15 days, 3 and 6 months. The first CT scan showed a small perigraft circulating false aneurysm which totally disappeared on the last exam. This case emphasizes the potential role of CT scan in the follow-up of patient after aortic surgery and the likely favorable outcome of some false aneurysm.
