Staphylococcal meningitis: a complication of psoas abscess
Neurology
|January 1, 1985
Abstract:
A previously healthy 59-year-old woman presented with fever, neck stiffness, and localized back tenderness. Spinal fluid and blood cultures grew Staphylococcus aureus. A diagnosis of pyogenic meningitis was made, but further investigation revealed that the meningitis arose from a clinically occult psoas abscess.
Insights
A psoas abscess caused Staphylococcus aureus meningitis in a healthy woman. This case highlights the importance of considering deep-seated infections when diagnosing meningitis.
Area of Science:
- Infectious Diseases
- Neurology
- Medical Diagnostics
Background:
- Pyogenic meningitis is a serious infection of the central nervous system.
- Staphylococcus aureus is a common pathogen causing various infections, including meningitis.
- Psoas abscesses are collections of pus in the iliopsoas muscle, often originating from spinal or abdominal sources.
Observation:
- A previously healthy 59-year-old woman presented with classic meningitis symptoms: fever and neck stiffness.
- She also reported localized back tenderness, suggesting a spinal or musculoskeletal origin.
- Cultures of cerebrospinal fluid and blood identified Staphylococcus aureus as the causative agent.
Findings:
- Initial diagnosis focused on pyogenic meningitis based on clinical presentation and positive cultures.
- Further investigations revealed an underlying, previously undetected psoas abscess.
- The meningitis was determined to be a complication stemming from this occult psoas abscess.
Implications:
- This case underscores the necessity of a comprehensive diagnostic approach in suspected meningitis.
- Clinicians should consider deep-seated infections, such as psoas abscess, as potential sources of central nervous system infections.
- Early identification and treatment of occult abscesses are crucial for managing complex infectious disease presentations.
