Rupture of Popliteal Arterial Aneurysm due to Salmonella Infection

bacteremia are not common. However, salmonella can involve the thoracic and abdominal aorta, as well as the coronary arteries and peripheral arteries, or it can involve vascular grafts and prosthetic valves (1, 2). Benenson et al. (3) reported that adult patients over the age of 50 with nontyphoidal salmonella bacteremia developed life-threatening vascular complications. In humans, typhoidal and nontyphoidal salmonella infections are most often associated with contaminated foods, and such infections may be divided into four groups: gastroenteritis, enteric fever, bacteremia with or without localized extraintestinal infection, and an asymptomatic chronic carrier state. CT is considered useful for the diagnosis and follow-up of salmonella aneurysms before surgery (4). Some reports have presented findings on aortic aneurysms that were already established at the time of diagnosis, and relatively few of these aneurysms showed progression from a normal or dilated aorta to marked dilatation or rupture (2, 3, 5). Rupture of a salmonella aneurysm, like the one seen in our case, demonstrates the dynamic course of this pathology in the popliteal artery and how rapid its evolution can be, and this has not been previously reported on.
