The lack of specific symptoms and signs in patients with tuberculous meningitis makes early diagnosis difficult. In this report, we reviewed the clinical features and laboratory findings of 6 infants with central system nervous tuberculosis during a 10-year period. One of the patients had multifocal tuberculosis. The mean time to the diagnosis was 32 +/- 13.4 days. A contact source was identified in only 2 patients. All 6 patients had abnormal cerebrospinal fluid findings, less than 500 cells/microL with lymphocytic predominance. Computerized tomography (CT) and/or magnetic resonance imaging (MRI) revealed hydrocephalus with basal enhancement in 2 patients. One patient developed pontocerebellar and pituitary tuberculomas, which were responsible for compression and diabetes insipidus, 1 year after antituberculous treatment. These localizations are very rare. On the follow-up, 3 patients had hypoacousia and only 1 had severe sequelae, despite a diagnostic delay.
