Brain abscess in infants and children.

Abstract

Forty-four consecutive patients with brain abscesses, aged between 1 month and 16 years, were reviewed. The cause of abscess was meningitis in 36% of the cases, otitis in 27%, head injury in 16%, congenital heart disease in 9%, other in 5%, and undetected in 5%. Thirty patients had a single abscess and 12 had multiple abscesses. Multiloculated abscess was present in 2. Total excision was accomplished in 22 patients. Three patients underwent needle aspiration. Drainage of the abscess was performed in 13. Secondary excision was needed in 5 patients. One patient was treated nonsurgically. Streptococci, staphylococci and Proteus mirabilis were the microorganisms recovered in cultures. Overall mortality was 20% (9 patients). Mortality was significantly higher in patients under 2 years of age than in those older. Of 15 patients who were comatose at the time of admission, 6 died. Etiology, diagnostic method, and treatment modalities were not found to be significant factors in terms of predicting mortality.
