Listeria monocytogenes: a rare cause for an infected abdominal aortic aneurysm.

Abstract

Infected aneurysms associated with Listeria monocytogenes are rare. We describe a case of an infrarenal abdominal aortic aneurysm infected by Listeria monocytogenes. The aneurysm was diagnosed using a contrast-enhanced computed tomography (CT) scan and the infective organism identified within positive blood cultures. The patient underwent a successful urgent open aortic aneurysm repair and completed a 6-week course of antibiotics.
