is not common, but the incidence is on the increase and has been attributed due to improved case notification, a rise in the elderly population, high rates of TB among new immigrants, increase in the prevalence of poverty and homelessness and the HIV epidemic. TB meningitis is associated with high morbidity and mortality. Early diagnosis can be difficult due to nonspecific early presentation and the disease is fatal if not treated early. The outcome of TB meningitis depends on the degree of neurological deterioration that has occurred by the time antituberculous
therapy is started. A tuberculoma
in the cerebral cortex
(arriving there by haematogenous spread) may enlarge and rupture with dissemination of bacilli and development of meningitis. Brain damage
resulting from the infection may cause motor paralysis, seizures, mental impairment, and abnormal behavior.
