Abstract:
This report describes a rare case of a pyogenic brain stem abscess. The lesion was readily identified by computed tomographic (CT) scan and magnetic resonance imaging (MRI). Streptococcus anginosus was grown from the pus and Actinomyces colonies were found on histopathology. The lesion was successfully treated with stereotactic surgery and antibiotic therapy. A review of the relevant literature including the role of stereotaxy in the treatment of the brain stem abscess is discussed. Copyright 1999 Harcourt Publishers Ltd.
