The infection spreads hematogenously from a distant focal tuberculoea, usually pulmonary tuberculosis and lodges immediately deep to the pia forming Rich foci. The treatment of TB meningitis is isoniazidrifampicinpyrazinamide and ethambutol for two months, followed by isoniazid and rifampicin alone for a further ten months.
Meningitis and other diseases of meninges G00—G03— ELISPOT testing is not useful for the diagnosis of acute TB meningitis and is often false negative,  but may paradoxically become positive after treatment has started, which helps to confirm the diagnosis.
