[Clinical contribution and cerebrospinal fluid study in reticulo-histiocytic meningoencephalitis].

A case of reticulo-histiocytic meningoencephalitis is reported. Changes in the fluid cell pictures, especially giant cells and mitoses are described. Obviously, reticulo-histiocytic encephalitis and neoplastic reticulosis are different stages of development and malignity of a uniform process, the etiology of which has not been understood until now but in which an immunological reaction in the sense of a delayed type of hypersensitivity plays a considerable part.
