Abstract:
Enterococcal meningitis is a rare complication of neurosurgical procedures. We present a patient who developed vancomycin-resistant enterococcal ventriculitis - meningitis after a brain tumor resection and ventriculoperitoneal shunt placement, treated successfully with intrathecal streptomycin through bilateral cerebrospinal fluid drainage catheters in addition to systemic antibiotics. This is the first report of such treatment for this resistant organism.
Insights
Vancomycin-resistant enterococcal meningitis, a rare neurosurgical complication, was successfully treated with intrathecal streptomycin. This novel approach offers hope for managing difficult-to-treat central nervous system infections.
Area of Science:
- Neurosurgery
- Infectious Diseases
- Microbiology
Background:
- Enterococcal meningitis is a rare but serious complication following neurosurgical interventions.
- The rise of vancomycin-resistant enterococci (VRE) presents significant challenges in treating central nervous system infections.
Observation:
- A patient developed ventriculitis-meningitis caused by vancomycin-resistant enterococci post-brain tumor resection and shunt placement.
- Standard antibiotic regimens were insufficient to clear the infection.
Findings:
- Successful treatment was achieved using intrathecal streptomycin delivered via bilateral cerebrospinal fluid drainage catheters, alongside systemic antibiotics.
- This represents the first reported case of successful management of vancomycin-resistant enterococcal meningitis with this specific therapeutic strategy.
Implications:
- Intrathecal streptomycin may be a viable therapeutic option for refractory vancomycin-resistant enterococcal meningitis.
- This case highlights the importance of exploring alternative treatment modalities for multidrug-resistant organisms in neurosurgical patients.
- Further research is warranted to evaluate the efficacy and safety of intrathecal streptomycin for central nervous system infections.
