title: Mycotic aneurysm due to Yersinia enterocolitica.
abstract: Infections of the cardiovascular system, besides involving both natural and prosthetic heart valves, vascular grafts, and indwelling venous and arterial cannulas, may cause mycotic aneurysms. The latter frequently complicate endocarditis; however, they may occur as isolated phenomena. Enterobacteriaceae are uncommon etiologic agents in vascular infections; however, a patient is reported who presented initially with a bacteremia due to Yersinia enterocolitica biogroup 4 and despite antimicrobial therapy developed a mycotic aneurysm of the left internal carotid artery. Clinical manifestations, pathogenesis, and treatment of yersiniosis are reviewed.
