Tuberculous meningitis.

Ten patients with confirmed tuberculous meningitis were seen at Meilahti Hospital, University of Helsinki, in 1966--1977. Six of the patients had a positive CSF culture for M. tuberculosis, and a positive CSF smear for acid-fast bacilli was found in one case. On admission, seven patients had an altered state of consciousness, five complained of headache, and nuchal rigidity was noted in two. Five patients recovered completely, three had persistent late sequelae, and two of the patients died. The most important fact influencing the prognosis was an early institution of adequate antituberculous chemotherapy.
