Evolution of salmonella aortitis towards the formation of abdominal aneurysm.

We present a case of salmonella aortitis with necrosis of the arterial wall and its evolution to the formation of an abdominal aneurysm over a 6-day period. Computed tomography was performed before and after the development of a mycotic aneurysm. Presurgical aortography was also performed. The findings obtained give a dynamic concept to this pathology and show its rapid evolution in a short period of time.
