Mycotic Thoracic Aortic Aneurysm Due to Salmonella Kentucky Infection

Mycotic aortic aneurysms (MAAs) are infective aneurysms that are associated with catastrophic outcomes if not diagnosed and treated on time. Less than 3% of all aortic aneurysms are mycotic and are mostly seen in the abdominal aorta. Staphylococcus aureus, Salmonella, and Pseudomonas aeruginosa are the most common causative organisms for MAAs. Salmonella species commonly cause infection in humans and occasionally result in serious complications, like mycotic aneurysms. Salmonella, Typhimurium (serogroup B), Enteritidis (serogroup D), and Choleraesuis (serogroup C) are the most common strains found to be associated with MAA. We present the first case of mycotic aneurysm likely secondary to Salmonella Kentucky infection.
