Central nervous system tuberculosis in children: a review of 30 cases

Abstract

The medical records of 30 children with central nervous system tuberculosis (CNS tuberculosis) who were treated between March, 1976, and February, 1989, were reviewed. All had cranial computerized tomography scans at presentation. The mean cerebrospinal fluid leukocyte count was 200/mm3, protein 239 mg/dl, glucose 25 mg/dl and CSF/serum glucose ratio 21%. Mantoux skin tests with 5 tuberculin units were greater than or equal to 10 mm induration in 50%, and chest radiographs were positive in 40% of patients. Hydrocephalus was demonstrated by cranial computerized tomography in all 30 patients (100%). Cranial computerized tomography scan demonstrating hydrocephalus is a sensitive radiographic nervous system tuberculosis and should be part of the early evaluation of children with suspected central nervous system tuberculosis.
