title: Abdominal septic aortic pseudoaneurysm caused by Campylobacter jejuni infection: report of a case.
abstract: Campylobacter jejuni infection is one of the most common bacterial causes of acute gastroenteritis worldwide. An extraintestinal manifestation is rare and, to our knowledge, an aortic aneurysm has until now never been documented. We report a case of a 72-year-old patient with a septic aortic pseudoaneurysm caused by C. jejuni infection. Computed tomography and magnetic resonance imaging showed a pseudoaneurysm in the abdominal aorta. The preoperative blood culture indicated a Gram-negative bacillus, which was identified 7 days later as C. jejuni. An aneurysmectomy, extensive debridement, and an in situ graft wrapped with the omentum were done, and the patient was given a 6-week course of antibiotics. Despite readmissions for abdominal infection and Salmonella bacteremia, a graft infection did not develop. In the 3 years since the procedure the patient has shown no signs of a relapse.
