Computed tomography in cranial tuberculosis.

Twelve patients with proven tuberculosis were studied by computed tomography. Three had tuberculomas and nine had tuberculous meningitis. Although a definite diagnosis is often not possible on CT, the method is of value in determining number, location and extent of lesions. In patients with tuberculous meningitis, CT is helpful in assessing the degree of hydrocephalus and in evaluating the effectiveness of antituberculous therapy.
