TB meningitis (Tuberculous meningitis) is caused by the Mycobacterium tuberculosis bacteria. Infection begins elsewhere in the body, usually the lungs, but in about 1 - 2% of cases the bacterium causes TB meningitis. TB meningitis Characteristic cerebrospinal fluid (CSF) findings of TBM include a lymphocytic-predominant pleiocytosis, elevated protein, and low glucose.
