Mycotic (infected) aneurysm of the popliteal artery and arthritis following Salmonella bacteriemia.

We report a case of a mycotic (infected) aneurysm of the popliteal artery due to Salmonella enteritidis. The clinical presentation may be confused with other more common causes of diffuse swollen leg, causing a delay in the diagnosis and proper therapy. Prompt surgical resection of the infected aneurysm together with medical therapy is required for successful treatment.
