Evaluation of Short-Term Neurological Outcomes in Children with Brain Abscesses

AIM: To evaluate the neurological outcomes of children diagnosed with brain abscesses in the early post-treatment period. MATERIAL AND METHODS: This study was a retrospective analysis of pediatric brain abscess patients between January 2000 and December 2015, during a 16-years period. Patients were divided into two groups according to their outcome at the end of the treatment. The patients with "good outcome" were the ones without any neurological sequelae [Glasgow Outcome Scale (GOS) score 5]. "Unfavorable outcome" was defined as having any kind of neurological deficit (GOS score 1-4). RESULTS: A total number of 31 patients (22 male, 71%) with the median age at diagnosis of 84 months (range, 1-202 months) were enrolled in this study. The most common presenting symptom was fever being encountered in 71% of the patients (n=22), followed by focal neurological deficit (FND)(n=17, 54.8%), vomiting (n=14, 45.2%), headache (n=13, 41.9%), seizure (n=13, 41.9%), change in mental status (n=12, 38.7%) and visual disturbance (n=2, 6.5%). Twenty-four patients (77.4%) had predisposing factors. The most common pathogens were gram-positive cocci (n=9, 29%). Seventeen patients (54.8%) had unfavorable outcome; 2 patients (6.4%) died. All patients were treated with parenteral antibiotherapy with median duration of 73 days (range, 28-540 days). Surgical procedures were performed in 83.9% (n=26) of patients [isolated aspiration (n=19, 61.3%), only resection (n=5, 16.1%), aspiration and resection (n=2, 6.5%)]. CONCLUSION: Glasgow coma scale score below 12 and the presence of FND on admission were found to be independent risk factors for unfavourable neurological outcome in children with brain abscesses.
