title: Brain abscess in children.
abstract: OBJECTIVE
  To find out the clinical presentation, radiological characteristics, various underlying predisposing conditions and causative organisms of brain abscess in children in our setup.
  
  
  METHODS
  Descriptive study.
  
  
  METHODS
  The Children's Hospital and the Institute of Child Health, Lahore, over two years from September 2001 to August 2003.
  
  
  METHODS
  All children (< 16 years) presenting with brain abscess were included to study demographic, clinical and radiological features. In addition, attempts were made to find out underlying predisposing conditions and causative organisms.
  
  
  RESULTS
  Twenty-five children with brain abscess were managed over 2 years. The mean age was 7.8 years (range 9 months to 16 years). Male to female ratio was 2.1:1. Most patients (43%) presented with 4 weeks history of illness, with mean duration of illness at presentation of 29.3 days. Main presenting complaints were fever (72%), vomiting (48%), headache (44%) and convulsions (32%). Five patients (20%) had papilledema at presentation, another 4 (16%) had paresis/paralysis and 3 (12%) had cranial nerve palsies. Majority (64%) had solitary abscess, located in parietal, temporal, frontal and occipital lobes in order of frequency. No underlying predisposing condition was identified in 8 (32%) cases; while 8 (32%) had cyanotic congenital heart disease, 5 (20%) patients had otic infection (mastoiditis), 2 (8%) were postoperative cases and one each developed brain abscess secondary to ventriculo-peritoneal (VP) shunt infection and pulmonary tuberculosis. Causative organisms were isolated in 40% cases, which included staphylococcus aureus, Staphylococcus epidermidis, Streptococcal species, Klebsiella, E. coli and Proteus.
  
  
  CONCLUSIONS
  Awareness of predisposing factors, early recognition of clinical features and understanding of the prevalent microbial profile is imperative for better management of children with brain abscess.
