[Detection and follow up of inflammatory lesions of the central nervous system by means of cytological study of the cerebrospinal fluid (author's transl)].
Cytocentrifugation gives an excellent quantitative and qualitative preservation of the cerebrospinal fluid cells. This method permits the study various types of meningeal or ventricular inflammatory changes (acute inflammatory changes with granulocytes, immunitary type or macrophagic changes) and causal diagnosis. During meningitis following bleeding or neurosurgical operation, repeated cytological examinations allow a simple but useful follow up of the evolution during the treatment.
