Brain abscess: a study of brain abscesses 1970 - 1979

Abstract

A series of 41 patients with intracranial abscess over a 10 year period (1970-79) were analysed and discussed. The incidence was 4 cases per year with a male to female ratio of 2:1. The mortality was 29.2 per cent. The most frequent findings were headache? confusion, nausea and vomiting. Signs of visual disturbance were commonly recorded with pupillary inequality seen in 34:1 per cent. Papilloedema was relatively uncommon but meningeal irritation and pyrexia were quite common. The value of lumbar puncture in relation to its inherent dangers is rated insignificant. Angiography is considered the most important single diagnostic method. The introduction of CAT-scan is considered long overdue. The various causes of brain abscess are discussed. Trauma) otogenic and post-operative causes were the most common in that , order. Meningitis and sinusitis were not significant causes. The various treatment protocols are also discussed. Excision of the abscess was more commonly used and was the treatment of choice in all those cases where aspiration failed to effect a cure.
