Abstract:
Gram-negative bacilli such as Pseudomonas aeruginosa are a rare cause of meningitis. Patients developing P. aeruginosa meningitis most commonly have a history of neurosurgical procedures. We report a patient who presented with community-acquired chronic meningitis secondary to P. aeruginosa, related to surgery for otosclerosis 5 years previously.
Insights
Pseudomonas aeruginosa meningitis is rare, often linked to neurosurgery. This case highlights a community-acquired chronic P. aeruginosa meningitis linked to otosclerosis surgery five years prior.
Area of Science:
- Neurology
- Infectious Diseases
- Microbiology
Background:
- Gram-negative bacilli are infrequent causes of meningitis.
- Pseudomonas aeruginosa meningitis is typically associated with prior neurosurgical interventions.
Observation:
- A patient presented with symptoms of chronic meningitis.
- The meningitis was community-acquired and diagnosed as P. aeruginosa.
Findings:
- The patient had undergone surgery for otosclerosis five years before the meningitis diagnosis.
- This case represents a rare instance of community-acquired chronic P. aeruginosa meningitis with a delayed post-surgical complication.
Implications:
- Highlights the potential for delayed central nervous system infections following otologic surgery.
- Suggests considering P. aeruginosa in the differential diagnosis of chronic meningitis, even in community-acquired cases without typical risk factors.
- Underscores the importance of long-term monitoring for infectious complications after otosclerosis surgery.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
