Abstract
Brain abscesses are rare in infants and their clinical presentation is specific for this age group. Seven cases of brain abscess in infants aged 2–11 months are reported. The underlying cause was meningitis in four, sepsis in two, and unknown in one. Gram-negative organisms were cultured in 6 patients. The abscess size was 5 cm or more in five cases; in four there were multiple lesions. Two abscesses were aspirated and irrigated; four particularly large lesions were drained and repeatedly aspirated and irrigated. One craniotomy was done. There were two deaths, one in the postoperative period and the other 6 months after discharge. Follow-up information is available for four children, showing a good result in only one of them. Formation of an abscess should be diagnosed early, and close ultrasound monitoring or CT scanning in infants with bacterial meningitis and sepsis is essential. The prognosis in cases in which large/multiple abscesses develop is poor.
