Summary
This case highlights rare cerebral ischemia from Streptococcus bovis endocarditis. Hemianopsia preceded diagnosis, emphasizing the need for early recognition of this serious complication.
Area of Science:
- Neurology
- Infectious Diseases
- Cardiology
Background:
- Infective endocarditis caused by Streptococcus bovis is uncommon.
- Cerebral ischemic events are rare complications of S. bovis endocarditis.
Observation:
- A 50-year-old man presented with frontal, parietal, and occipital lobe cerebral ischemia.
- Hemianopsia was the initial symptom, preceding the diagnosis of S. bovis endocarditis.
- Clinical presentation initially suggested systemic vasculitis.
Findings:
- Vegetating lesions were identified on the aortic valve.
- Blood cultures confirmed the presence of Streptococcus bovis.
- Antibiotic therapy and aortic valve replacement successfully treated the infection and prevented further thromboembolic events.
Implications:
- This case expands the understanding of rare neurological manifestations of S. bovis endocarditis.
- Early recognition of symptoms like hemianopsia is crucial for timely diagnosis and management.
- The absence of mucosal lesions in this case suggests alternative, yet to be identified, portals of entry for S. bovis.
