Structural changes in the brain according to computed tomographic data in patients undergoing combination therapy for hemispheric gliomas

: Basing on CT data, the authors analyze the qualitative changes in the brain of patients with a history of multiple-modality treatment for immature neuroectodermal tumors. Plani- and volumetric parameters of the total brain, the involved and the contralateral hemispheres are compared with the same parameters in the reference group. The pattern and degree of structural changes were found related to the site of the tumor and surgery. The brain matter in both hemispheres was lost mostly in the interstitial and end portions predominantly on the side of the tumor and surgery. Changes of the brain were individual in the patients.
