Mycobacterium tuberculosis meningitis and other etiologies of the aseptic meningitis syndrome.

Mycobacterium tuberculosis is one of the most common infectious agents in the world. It causes an insidious form of meningitis characterized by headache, low-grade fever, stiff neck and cranial nerve palsies, and an acute meningoencephalitis characterized by coma, raised intracranial pressure, seizures, and focal neurological deficits. This review focuses on the diagnosis and therapy of the insidious form of tuberculous meningitis and discusses the differential diagnosis of infectious and noninfectious etiologies of the aseptic meningitis syndrome.
