Summary
Streptococcus constellatus can cause rare myocardial abscesses and cerebritis. This case highlights the aggressive nature of S. constellatus infections, even with treatment.
Area of Science:
- Infectious Diseases
- Cardiology
- Neurology
Background:
- Streptococcus constellatus is an uncommon pathogen.
- Myocardial abscess and cerebritis are rare complications of S. constellatus infections.
Observation:
- A 21-year-old woman presented with fever, diarrhea, and S. constellatus bacteremia.
- Brain imaging revealed severe cerebral swelling, indicative of cerebritis.
- Echocardiography identified a cystic lesion on the left atrium, suggesting a myocardial abscess.
Findings:
- Despite broad-spectrum antibiotics (penicillin G and ceftazidime) and supportive care, the patient's condition rapidly deteriorated.
- Cerebrospinal fluid and blood cultures confirmed S. constellatus as the causative agent.
- The patient succumbed to the infection due to persistent increased intracranial pressure.
Implications:
- This case underscores the critical need for prompt recognition and aggressive management of S. constellatus infections.
- It highlights the potential for S. constellatus to cause severe cardiac and neurological complications.
- Further research into the pathogenesis and optimal treatment strategies for S. constellatus infections is warranted.
