title: Tuberculous meningitis: a clinical and laboratory study of 20 patients in Qatar.
abstract: Twenty cases of tuberculous meningitis were diagnosed at the Hamad Medical Corporation between 1990 and 1995. Most of the patients (90%) were expatriates. The most common presenting features were fever, headache, neck stiffness and altered mental status. Five patients were in stage 1 disease at the time of presentation, 11 in stage 2, and four in stage 3. Examination of cerebrospinal fluid showed at least one abnormal finding in all patients, and culture grew Mycobacterium tuberculosis in 50%. A positive tuberculin skin test in 50% of patients, abnormal chest X-ray in 35%, abnormal CT scan or MRI showing tuberculoma or hydrocephalus in 55%, and positive sputum culture for M. tuberculosis in 15% helped establish the diagnosis. All the patients were treated with antituberculous drugs and steroids. Seventeen (85%) survived, three with severe neurological sequelae; three (15%) died. Poor outcome was associated with advanced stage of disease at presentation and high CSF protein. Tuberculous meningitis continues to be an important disease in Qatar, especially in expatriates, and should be considered in the differential diagnosis in any patient presenting with fever and change in sensorium.
