Nocardial cerebral abscess: Report of three cases and review of the current neurosurgical management

Nocardia asteroides cerebral abscesses are rare but challenging intracranial lesions. Early diagnosis, institution of appropriate antimicrobial therapy, lack of underlying systemic disease and limited intracranial disease are recognized factors leading to good outcome. However, the optimal treatment approach has not been established and nocardial brain abscesses have been managed either conservatively, with stereotactic aspirations or with open craniotomy and enucleation. We present three cases of Nocardia asteroides cerebral abscesses cured only after neurosurgical enucleation, and discuss the current management alternatives and conclude that a more aggressive approach than that currently preferred for this entity may be more effective.
