Concurrent Salmonella mycotic abdominal aneurysm and empyema thoracis: a rare coincidence
1Renal Division, Department of Internal Medicine, National Taiwan University Hospital Jin-Shan Branch, New Taipei, Taiwan, ROC.
Objective:
To present a case of Salmonella bacteremia with a rare metastatic focus.
Clinical Presentation And Intervention:
A 61-year-old male presented with a suicide attempt after ingestion of half a bottle of toilet cleaner. He had a medical history of intravenous drug abuse and major depression. Persistent Salmonella enteritidis bacteremia occurred during his hospitalization, and a search for the primary source of infection disclosed a mycotic abdominal aortic aneurysm. A suppurative lesion was also noted over the left pleural space, and Salmonella empyema was confirmed after thoracentesis. He underwent video-assisted thoracoscopic surgery and endovascular repair of the abdominal aortic aneurysm and was placed on long-term antibiotics, without recurrence.
Conclusion:
S. enteritidis involvement of the cardiovascular system is a rare coincidence and results in significant morbidity and mortality. In addition, the phenomenon of secondary metastatic infective foci involving the pleural space has an even lower frequency than that of cardiovascular involvement. Therefore, a high index of suspicion and prompt treatment from the treating physicians are strongly recommended.
Insights
This case report details a rare instance of Salmonella enteritidis bacteremia leading to a mycotic abdominal aortic aneurysm and Salmonella empyema. Prompt diagnosis and treatment are crucial for managing these severe, uncommon infections.
Area of Science:
- Infectious Diseases
- Cardiovascular Medicine
- Pulmonology
Background:
- Salmonella bacteremia is a serious condition, often originating from the gastrointestinal tract.
- Cardiovascular and pleural space involvement represent rare but severe metastatic complications.
Observation:
- A 61-year-old male with a history of intravenous drug abuse and depression developed persistent Salmonella enteritidis bacteremia after a suicide attempt.
- Infection led to a mycotic abdominal aortic aneurysm and a secondary Salmonella empyema in the left pleural space.
Findings:
- The patient underwent surgical repair of the abdominal aortic aneurysm and video-assisted thoracoscopic surgery for the empyema.
- Long-term antibiotic therapy resulted in successful treatment without recurrence.
Implications:
- This case highlights the importance of considering rare metastatic complications in Salmonella bacteremia.
- Early recognition and aggressive management are vital for improving outcomes in patients with cardiovascular and pleural Salmonella infections.
