Stereotactic aspiration of brain abscesses: is this the treatment of choice?
Despite a reduction in the mortality of patients with brain abscess since the introduction of the computed tomography (CT) scanner, controversy persists as to the preferred method of treatment for this condition. Eleven patients were treated by CT guided stereotactic aspiration of pus and appropriate antibiotic therapy. A total of 14 aspirations were performed. Ten abscesses were supratentorial and one was in the posterior fossa. In 9 patients a bacterial cause was identified while in 2 a fungus was identified. A good outcome was achieved in 7 patients but 3 patients died. Another elderly patient remains disabled at home. The deaths occurred in severely systemically ill patients with poor conscious levels on admission. Only one patient has epilepsy, controlled with anticonvulsants while another has not had further seizures since abscess treatment a year ago. Stereotactic aspiration should be considered the treatment of choice in all but the most superficial and largest cerebral abscesses, although the mortality of this condition in the severely ill remains high.
