A rare case of infective endocarditis (IE) caused by Granulicatella adiacens led to a fatal left ventricular pseudoaneurysm. Autopsy revealed subtle clinical symptoms and highlighted catastrophic complications of this rare IE cause.
Area of Science:
- Cardiology
- Infectious Diseases
- Pathology
Background:
- Infective endocarditis (IE) is a serious heart valve infection.
- Complications include valve damage, abscesses, and fistulas.
- Atypical complications like pseudoaneurysms are rare but critical.
Observation:
- A 19-year-old male presented with fever and cough.
- Autopsy revealed aortic valve vegetations and a left ventricular pseudoaneurysm.
- Granulicatella adiacens was identified as the causative agent.
Findings:
- The pseudoaneurysm was a periannular hemorrhage within the myocardium.
- Vegetations showed necrotic, hollow areas with blood clots.
- Positive anti-streptolysin O titre (ASOT) indicated a possible streptococcal link.
Implications:
- IE caused by Granulicatella species is uncommon and can have severe outcomes.
- This case highlights the importance of recognizing subtle clinical signs of IE.
- Autopsy findings are crucial for understanding rare IE complications.
