Brain abscess: a review of recent experience

Abstract

From 1961 through 1973, 60 patients with brain abscess were treated at the Mayo Clinic by surgical excision and antimicrobial therapy. The operative mortality was 17%, which was identical to a similar series reported in 1959. The patients who had the diagnosis of brain abscess confirmed at autopsy and who never underwent operation (24 patients) were more elderly than the group operated on, and a higher percentage had multiple brain abscess. Severe systemic disease or multisystem disease, or both, usually precluded a vigorous surgical approach among the nonsurgical group. Etiologic, diagnostic, and microbiologic factors were examined to develop an approach to antimicrobial therapy.
