[Midbrain structures and the cerebrospinal fluid circulation system in central nervous system disease].

The author offers an original method of the study of the midbrain structures and liquor circulation system (the third ventricle, brain water-pipe, the fourth ventricle) in the small cavity in the course of autopsy. The position of the middle structures is characterized by means of the angle measuring of their borders against bone structures of the base and vault of the skull. The method allows to assess morphometrically the degree of dislocation of the middle structures in pathological conditions accompanied by brain edema.
