[Use of a stereotaxic method in the diagnosis and treatment of brain neoplasms in children].

The paper presents the possibility of application of the stereotactic method in the diagnosis and treatment of pediatric brain tumours, based on the material of the Dept. of Stereotactic Neurosurgery of the University Clinic in Homburg-Saar (Germany). The basic theoretical principles and diagnostic potential of serial biopsy and intraoperative diagnosis are presented. Shown are new therapeutic possibilities created by interstitial brachytherapy. The results obtained in stereotactic treatment of brain tumours are deemed satisfactory, as the method enables a cause-oriented treatment in cases hitherto inoperable because of localisation and resistant to megavolt radiotherapy because of radiobiological characteristics of the given neoplasm.
