title: Rapidly enlarging iliac aneurysm secondary to listeria monocytogenes infection: a case report.
abstract: Infected aneurysms caused by Listeria monocytogenes are rare. Worldwide, 16 cases have been reported, none in the iliac system. The authors report the case of an 80-year-old man being followed for small aortic and right common iliac artery (RCIA) aneurysms who presented with progressive gastrointestinal symptoms. Serial computed tomography demonstrated a 200% increase in RCIA diameter with development of infection over 1 month. Right axillobifemoral bypass and aneurysm resection were performed. The authors believe this case represents the first description of bacteremic seeding of an iliac degenerative aneurysm by Listeria monocytogenes. The natural history and aggressive course of vascular infection with this organism are documented.
