Introduction:
Brain abscesses arising from right-to-left cardiac shunting are very rare in adults.
Case Presentation:
We describe the case of a 47-year-old non-hispanic white male with periodontal disease who developed several brain abscesses caused by Streptococcus intermedius. A comprehensive workup revealed a patent foramen ovale with oral flora as the only plausible explanation for the brain abscesses.
Conclusion:
Based on this case and the relevant literature, we suggest an association between a silent patent foramen ovale, paradoxical microbial dissemination to the brain, and the development of brain abscesses.
Insights
A rare case of brain abscesses in an adult was linked to a patent foramen ovale, a heart defect allowing paradoxical microbial spread. This highlights a potential cause for recurrent brain infections.
Area of Science:
- Neurology
- Cardiology
- Infectious Diseases
Background:
- Brain abscesses are uncommon in adults, especially when associated with right-to-left cardiac shunting.
- Periodontal disease can be a source of oral flora, a potential pathogen in brain infections.
Purpose of the Study:
- To present a rare case of multiple brain abscesses in an adult.
- To investigate the potential link between a patent foramen ovale and brain abscesses.
- To explore the mechanism of paradoxical microbial dissemination.
Main Methods:
- Case report of a 47-year-old male with periodontal disease and Streptococcus intermedius brain abscesses.
- Comprehensive diagnostic workup including cardiac evaluation.
- Literature review on patent foramen ovale and brain abscesses.
Main Results:
- A patent foramen ovale was identified as the likely source of right-to-left shunting.
- Oral flora was implicated as the causative agent, originating from periodontal disease.
- Multiple brain abscesses were successfully treated.
Conclusions:
- A silent patent foramen ovale may facilitate paradoxical microbial dissemination to the brain.
- This association could explain otherwise cryptogenic brain abscesses.
- Early detection of cardiac shunts may be crucial in managing recurrent brain infections.
