[Intraoperative sonographic localization of brain tumors].
Twenty-six patients with mostly small intracranial space-occupying lesions were examined sonographically during surgery. In all patients, accurate localisation and complete delineation of the intra-cerebral lesion proved possible. The extent of the lesion could be determined accurately and surrounding cerebral structures were identified unequivocally. There were no significant differences in the appearances before and after opening of the dura. The significant advantage of the intra-operative use of sonography lies in the accurate localisation of the space-occupying lesion. This results in a reduction of interference with normal cerebral tissue and in a reduction of the duration of the operation.
