[Salmonella aortitis in an elderly patient : clinical case and review of the literature].

Gastroenteritis due to non-typhoidal Salmonella (NTS) is usually considered as a benign infection. NTS can nevertheless cause severe diseases with high mortality. Invasive NTS infections may present as bacteremia without other manifestations, particularly in immunocompromised hosts. They may also correspond to extra-digestive infections in various body sites. Patients with cardiovascular diseases are at risk for endovascular infections, aortitis being the most frequent. These infections are difficult to diagnose and require surgery.
