title: Nocardial brain abscess: diagnostic and therapeutic use of stereotactic aspiration.
abstract: Three cases of nocardial brain abscess are presented. All three patients were receiving immunosuppressive therapy at the time of diagnosis. Two patients had cardiac transplantation and the third had periarteritis nodosa. The patients presented with generalized seizures or focal weakness. Accurate localization of the intracerebral mass lesion was obtained from computed tomography (CT) scans, but CT-guided stereotactic aspiration was required for diagnosis and treatment in every case. After Nocardia asteroides was seen on Gram's stain and subsequently identified by culture, appropriate antibiotic therapy was initiated. Both heart transplant patients survived in good neurological condition. We believe that stereotactic aspiration followed by prolonged antibiotic therapy may significantly improve the outcome of patients with nocardial brain abscess.
