Current philosophy of treatment of brain abscess includes aspiration, appropriate antibiotics, treatment of sequelae and eradication of the primary source. Early clinical suspicion and diagnosis with CT is crucial. Small abscesses (<3 cm) in cerebritis or capsular stage located deep in clinically stable, poor surgical risk patients with diagnosis firmly supported by CT, may be treated with medical treatment only. Biweekly CT scan must be done to monitor the treatment response. CT or ultrasound guided aspiration should be performed in the event of clinical deterioration, failure of reduction in size or enlargement of abscesses. Encapsulated abscess (>3 cm), presence of significant neurological deficit or mass effect, doubt in the diagnosis and presumed resistant organisms are best treated with aspiration. Excision is required in large superficial abscesses resistant to multiple aspirations, post-traumatic abscess with a foreign body or fistula and multiloculated abscess of nocardial or actinomycotic aetiology. Results are directly related to the sensorium at the time of presentation. Stereotactic aspiration of all the loculi of multiloculated abscess in single or staged aspiration, and more completed drainage and lavage with endoscopic stereotactic evacuation may cut down indications of excision of brain abscess in future. It is concluded that, with diagnostic and technical advancements, a trend of adequate drainage of brain abscess via minimally invasive surgery is emerging. Confirmation of diagnosis and monitoring of treatment response with magnetic resonance spectroscopy may allow greater number of patients in future to be managed with medical treatment only.
