A Case Report: Ruptured Popliteal Aneurysm Caused by Haemophilus Influenzae Infection.

Mycotic aneurysms arise from infection of an arterial wall secondary to septic emboli from endocarditis. Although rare, most mycotic aneurysms involve the abdominal aorta, with Staphylococcus aureus and Salmonella spp being the most common causative organisms. We report a case of an 81-year-old woman with a ruptured mycotic popliteal aneurysm from Haemophilus influenzae infection.
