[Cerebral arachnoiditis].

An examination of 200 patients with cerebral arachnoiditis has shown that the meningeal adhesions and cysts revealed on pneumoencephalography may be consequences of current or terminated chronic leptomeningitis and chorioependimitis. Characteristic of current inflammatory process are variability and progress of the neurological symptoms, increase of cytosis and, sometimes, of protein content in the CSF, as well as some hematological signs of an inflammation, such as relative lymphocytosis, positive test for the C-reactive protein, and dysproteinemia. Such a differentiation of cerebral arachnoiditis has enabled the authors to choose more rational therapeutic measures and to give an adequate evaluation of their efficacy.
