Tuberculous meningitis causes more deaths than any other form of tuberculosis. It often does not have the typical symptoms of fever or headache. This meningitis probably results from the rupture of a tuberculoma. A gelatinous exudate fills the basal cisterns, which will enhance with contrast. When the tuberculoma is over 2 cm., it tends to have a thick enhancing ring with little or no surrounding edema.
Solitary lesions are more frequent below the tentorium.
