Area of Science:

  • Neurosurgery
  • Infectious Diseases
  • Epidemiology

Background:

  • Brain abscess incidence varies globally.
  • A significant number of neurosurgery admissions are due to brain abscesses.

Purpose of the Study:

  • To report on the characteristics of brain abscess cases treated at King Faisal University and Dammam Central Hospital.
  • To identify common microorganisms, predisposing factors, affected areas, complications, and mortality rates.

Main Methods:

  • Retrospective case series of 26 brain abscess patients.
  • Analysis of patient demographics, clinical presentation, microbiological findings, and outcomes.
  • Data collected over a six-year period (1982-1988).

Main Results:

  • Young males were predominantly affected (M/F ratio 3.3:1).
  • Streptococcus was the most frequent microorganism (38.4%), with mixed infections in 15.3%.
  • Chronic otitis media and paranasal sinusitis were significant predisposing factors (57.6%); temporo-parietal area was the commonest site; epilepsy occurred in 30.7%; mortality rate was 15.3%.

Conclusions:

  • Brain abscesses represent a notable proportion of neurosurgical admissions in the region.
  • Prompt identification and management of predisposing conditions like chronic otitis media and sinusitis are crucial.
  • High rates of complications like epilepsy and significant mortality underscore the severity of brain abscesses.
