Overview
Laboratory Findings
Laboratory findings consistent with the diagnosis of brain abscesses include cerebrospinal fluid (CSF) analysis and erythrocyte sedimentation rate (ESR).[1]
- In one particular study, 41 out out 140 patients tested deteriorated within 48 hours of lumbar puncture, and out of those 41 patients, 25 died.
- Findings involving CSF are nonspecific.
- The ESR is usually elevated in the 40 – 50 range, but again, can also be normal.
- Patients usually have a moderate leukocytosis (< 20k), yet up to 40% can have a normal WBC count.
- Obtaining tissue is demonstrates the pathogen in close to 100% of cases.
