The purpose of this study is to investigate the evolution of primary brain abscesses to establish the rationale and timing for definitive treatment. We present a retrospective evaluation of the course of twenty consecutive patients with primary brain abscesses treated by antibiotic therapy and then by stereotactic aspiration assisted by impedance monitoring and implantation of an intracavitary device. At follow-up of 1-15 years (mean 9 years) there were no relapses of abscesses and all patients achieved definitive disappearance of focal neurological deficits and progressive normalization of the neuroradiological patterns. The peculiarity of this series of primary brain abscesses is the high incidence of 'sterile' purulent material aspirated from within these expanding brain lesions. The data reported suggest that 'sterile' brain abscesses may act as self-maintaining expanding lesions. This study confirms the therapeutic role of stereotactic evacuation of these life-threatening lesions.
