An Unusual Case of Mycotic Popliteal Aneurysm Presenting as Recurrent Salmonella enteritidis Bacteraemia

We describe a patient with a Salmonella enteritidis mycotic aneurysm. A 91-year-old man presented with recurrent episodes of S. enteritidis bacteraemia 2 months apart. During the second presentation, he underwent magnetic resonance imaging of the left lower limb that revealed rupture of the popliteal artery with a popliteal fossa collection. This was aspirated and cultures grew S. enteritidis. He underwent endovascular stenting and received a prolonged course of antibiotics. Popliteal artery mycotic aneurysm should be considered as a differential in patients presenting with unilateral painful leg swelling and bacteraemia from microorganisms with a propensity for endovascular infections
