BACKGROUND: Tuberculosis is an important illness with an increasing occurrence. Although considered primarily a pulmonary disease, tuberculosis can affect any organ system. Central nervous system involvement is potentially devastating and occurs with escalating frequency in both immunocompetent and immunologically incompetent populations. METHODS: This case report involved a patient admitted to the authors' inpatient service. Data were obtained from the patient's medical record. MEDLINE and Index Medicus literature searches were conducted for the years 1977 to the present, with cross-references for earlier articles. RESULTS AND CONCLUSIONS: A 36-year-old previously healthy, immunocompetent woman with a diagnosis of extrapulmonary tuberculosis and no determined primary focus was found to have a cerebellar abscess. Treatment included surgical excision of the abscess combined with 6 months of antituberculosis therapy. Diagnostic tools included the tuberculosis skin test, smears and culture of specimens, computed tomographic scans, and rapid assays based on nucleic acid amplification, ie, polymerase chain reaction. The polymerase chain reaction has great potential for rapid diagnosis of Mycobacterium tuberculosis, particularly when there might be few bacilli, as in pleural, peritoneal, or cerebrospinal fluid. Appropriate therapy for tuberculous cerebellar abscess includes standard antituberculosis medications for 6 to 9 months and surgical excision of the abscess.
