An Infected Aortic Aneurysm After Successful Treatment of Nontyphoidal Salmonella Gastroenteritis

A 75-year-old man was admitted to our hospital with diarrhea. He had a history of mitral valve plasty for mitral regurgitation, chronic heart failure, cerebral infarction, and type 2 diabetes mellitus. C-reactive protein (12.5 mg/dL), blood urea nitrogen (142.6 mg/dL), and creatinine (10.9 mg/dL) levels were increased remarkably. Colonoscopy showed redness and edematous mucosa at the terminal ileum and the total colon (Figure A). Nontyphoidal Salmonella (NTS) with O8 antigen was identified from cultures of stool and mucosa of the terminal ileum, although blood cultures were negative.
