[Polycystosis of the brain].

This paper presents a case with 11-year history of disseminated cerebral polycystosis in a 23-year-old female. Physical examination and CT, MRT, histological and biochemical data suggest that the disease is morphologically progressive; however, the spread on brain lesions showed no correlation with relatively mild clinical manifestations of the disease. Variants of nosological interpretation of histological data are discussed.
