title: [The involvement of the choroid plexus and ependyma in tuberculosis: its importance in dissemination of the disease in the central nervous system].
abstract: It is reported in this paper, the study of the choroid plexus and ependyma in 42 cases of tuberculous meningitis. Granulomatous lesions were found as a very frequent lesion in the choroid plexus (75%). In some cases detached granulomas were found free among the villi. The ependymal lesions seen in 97% of the cases are characteristic of the tuberculous granular ependymitis. The report points out the role of these lesions, played in the pathogenesis of the tuberculous meningitis.
