Central nervous system tuberculosis in children

Abstract

The incidence of tuberculosis in the United States is increasing in all age groups; 5% of all of these patients have central nervous system involvement. We studied childhood central nervous system tuberculosis between 1979 and 1989 and reviewed the literature for patients up to 14 years of age. The small number of patients reported in this country results in delayed diagnoses because of reduced awareness. Cranial computed tomography within 1 week of initial symptoms may reveal basilar enhancement, hydrocephalus, or infarction. When combined with cerebrospinal fluid findings atypical for common bacterial infection, these radiographic findings support the prompt initiation of antituberculous therapy. Prophylactic considerations are also discussed.
