[Neurology in processes of ventricles I-III].

Experience gained in a total of 254 patients who were treated in the last thirty years at the Leipzig hospital because of processes of the cerebral ventricles I-III shows that neurological diagnostics has preserved its value as a screening method and a method during the period of treatment also in the era of computer tomography. The functional variety of the structures surrounding the ventricles characterises the syndromes showing differences according to the localisation and size of the tumours. A fact complicating the assessment is the masking caused by symptoms of the cerebral pressure, in the postoperative phase, the symptoms frequently become even clearer and in case of vegetative disorders may take dramatic forms.
