Abstract
- Citrobacter freundii is frequently isolated in antimicrobial-resistant nosocomial infections. Many strains of Citrobacter freundii are capable of producing an inducible broad-spectrum beta-lactamase. We report a case of an abdominal aortic aneurysm infected with Citrobacter freundii. A 55-year-old woman presented with acute lower back pain. Contrast enhanced computed tomography revealed a saccular aneurysm of the infrarenal abdominal aorta, with impending rupture. She underwent emergency surgery, during which a segment of aneurysmal aorta and infected tissue were completely removed and an in situ graft was placed for vascular reconstruction. The anastomotic site and inserted graft were wrapped with greater omentum. Citrobacter freundii was isolated by tissue culture from the resected aneurysmal wall.
