[Cerebral x-ray computed tomography and tuberculous meningitis. Radio-clinical correlations]

Two cases of tuberculous meningitis showed that there is a delay between the C.T. images and the clinical signs. The computed tomography which was still normal one and two months after the first clinical signs did not permit an early diagnosis of the tuberculous meningitis. It did not give either, at least in the beginning, a good appreciation of the results of the treatment, since most of the C.T. images appeared and/or increased while the patient's conditions had already been improving under treatment for several days or weeks. In a long range, however, the C.T. images usually disappear.
