Summary
A distant focus of infection is the primary predictor of mortality in brain abscess patients. Early identification and management of this metastatic source are crucial for improving patient outcomes in neurosurgery.
Area of Science:
- Neurology
- Neurosurgery
- Infectious Diseases
Background:
- Brain abscess is a severe neurological condition associated with high morbidity and mortality.
- Understanding clinical presentation and mortality predictors is vital for effective patient management.
Purpose of the Study:
- To investigate the clinical presentation of brain abscess.
- To identify independent predictors of mortality in brain abscess patients.
Main Methods:
- Retrospective analysis of 66 brain abscess patients at a tertiary care hospital.
- Statistical analysis included univariate analysis and logistic regression.
Main Results:
- A distant metastatic focus of infection was the most common predisposing factor (29%).
- Streptococci were the most frequent isolates (39%), and sinusitis was notably absent as a contiguous source.
- Overall mortality was 29%, with a distant focus of infection identified as the sole independent predictor of mortality.
Conclusions:
- Age, corticosteroid use, multiple abscesses, lumbar puncture, and conservative management did not significantly impact outcomes.
- A distant metastatic source of infection is a critical determinant of mortality in brain abscess.
