Stereotaxy in Brain Abscess

ABSTRACT

Despite a reduction in the mortality of patients with brain abscess since the introduction antibiotics and computed tomography controversy persists as to the preferred method of treatment for this condition. Twenty two patients were treated by CT or MRI guided stereotactic aspiration or excision with appropriate antibiotic therapy. Thirteen patients who were treated by aspiration recieved a total of 6 to 8 weeks of antibiotic therapy. Eight patients who were treated by excision recieved a total of 1 to 2 weeks of antibiotic therapy. One patient was managed with biopsy followed by antibiotic therapy, but due to increase in size of abscess, open craniotomy was performed. Stereotaxy is a procedure with minimal morbidity and mortality. It should be considered in patients with small, multiple, or deep-seated abscesses, in those who are poor operative candidates, and in those who have failed prior therapy. Stereotactic excision may be considered in patients with small(< 20mm) superficially located abscesses.
