Summary
The prevalence of cavum septi pellucidi (CSP) is high in both boxers and controls. Boxers show a greater posterior extent of CSP, potentially due to increased intracranial pressure.
Area of Science:
- Neurology
- Radiology
- Sports Medicine
Background:
- Cavum septi pellucidi (CSP) significance is debated, especially in healthy individuals and boxers.
- Limited large-scale magnetic resonance imaging (MRI) studies exist for boxers.
Purpose of the Study:
- To determine the prevalence and extent of CSP in professional boxers.
- To compare CSP findings in boxers versus a control group.
Main Methods:
- Retrospective MRI review of 164 male boxers and 43 controls.
- Analysis of CSP prevalence, size, and extent (types 1, 2, 3).
- Assessment of parenchymal abnormalities and brain atrophy using the Evan's ratio.
Main Results:
- CSP present in 49% of boxers and 40% of controls; a trend towards higher prevalence in boxers.
- Boxers exhibited significantly greater posterior CSP extension (types 2 and 3) than controls.
- Increased CSP size over time observed in boxers with serial imaging, independent of age, without evidence of atrophy.
Conclusions:
- CSP is common in both boxers and controls, with boxers showing greater posterior extension.
- The findings suggest potential links between CSP changes and increased intracranial pressure in boxers.
- Serial imaging reveals CSP progression in some boxers, highlighting the need for further research into its long-term implications.
