[New evaluation possibilities of therapeutic results in gliomas using computerized tomography].

The therapy effect as well as the growing of the recidivity of gliomas is followed up by CT routine examinations because in this way the patient is not subjected to an unnecessary strain. The author establishes a CT syndrome of the growth activation of gliomas: Occurrence of a periofocal reaction around the focus, appearance of solid nodous structures in the tumour with enhancement, extension of the local cerebral oedema, development of a diffuse cerebral oedema with reaction of the ventricular system. The syndrome can already be proved 4 to 6 months (in case of the glioma grading being I and II) or 2-3 months (in case of gradings III and IV) before the clinical manifestation. Thus it permits to make objective statements with respect to the "life quality" and its proceeding in time.
