Summary
A Salmonella typhimurium infection led to a mycotic abdominal-aortic aneurysm in a patient. Prompt diagnosis and treatment of this rare condition are crucial for a positive outcome.
Area of Science:
- Infectious Diseases
- Cardiovascular Medicine
- Vascular Surgery
Background:
- Mycotic aneurysms, particularly those involving the aorta, are rare but serious complications of bacterial infections.
- Salmonella species are an uncommon but recognized cause of infectious aortitis and mycotic aneurysms.
- Understanding the link between urinary tract infections and subsequent aortic aneurysms is critical for early intervention.
Observation:
- A case report details a patient who developed a mycotic abdominal-aortic aneurysm caused by Salmonella typhimurium.
- The aneurysm was diagnosed four months after a urinary tract infection caused by the same pathogen.
- Transient salmonellal bacteremia, potentially from the initial UTI, is hypothesized as the source of infection.
Findings:
- Salmonella typhimurium was identified as the causative agent of the mycotic abdominal-aortic aneurysm.
- The patient's history included a preceding urinary tract infection with the same organism.
- Review of literature on Salmonella-induced arteritis, focusing on pathogenesis, clinical presentation, and management.
Implications:
- Early diagnosis and prompt, appropriate treatment of salmonellal mycotic aortic aneurysms are vital for patient survival and favorable outcomes.
- Increased clinical suspicion for bacteremia in patients with urinary tract infections, even if seemingly resolved, is warranted.
- This case underscores the importance of recognizing and managing invasive Salmonella infections to prevent severe vascular complications.
