Acute aortic occlusion from a Candida fungus ball

Abstract

Fungal arterial infections are well-described entities resulting in direct invasion of the arterial wall or embolic occlusion of small and medium-sized arteries. However, acute occlusion of large vessels such as the aorta by fungal material is exceedingly rare. A 53-year-old woman presented with acute bilateral lower extremity ischemia. She had a history of fungal endocarditis requiring two prosthetic mitral valve replacements; the last episode was 7 months before the current admission. Imaging studies revealed that she had an acute infrarenal aortic occlusion, with evidence of multiple end-organ emboli. After transfemoral thromboembolectomy, perfusion was restored to her lower extremities with minor neurologic sequelae. She ultimately responded to intravenous antifungal agents.
