Multilevel Mycotic Aneurysms Due to Salmonella Infection: Case Report and Review of the Literature.

Infected or mycotic aneurysms (MAs) of the aorta and adjacent arteries are rare and difficult to treat. We report a unique case of a Salmonella serotype enteritidis-induced rapidly expanding aortic and iliac pseudoaneurysm during preoperative workup. Based on the presented case, we postulate that the agressive nature of Salmonella enteritidis MAs should not be underestimated. If postponed intervention is chosen and the patient is managed conservatively with antibiotic therapy to create a window of definitive diagnosis, one should consider close follow-up imaging to observe progression of the pseudoaneurysm. This may prevent the need of acute intervention.
