title: [Application of navigation system ExacTrac in radiation therapy of a female patient with disseminated pineoblastoma].
abstract: Neuronavigation is a modem and perspective technique widely applied not only in neurosurgery but in radiation treatment of neurosurgical diseases as well. Radiographic control of patient and target positioning during irradiation increases accuracy and improves treatment outcomes. Application of neuronavigation significantly expands the possibilities of radiation therapy allowing irradiation of extracranial lesions, application of mask fixation for radiation treatment, and hypofractionated radiotherapy of intracranial and spinal targets. We describe 1 illustrative case of a female patient with 2 metastases of pineoblastoma located in left cerebellar hemisphere and at the level of CVII vertebra. Both lesions were irradiated in hypofractionated mode using ExacTrac XRay 6D neuronavigation system. After 7 months these foci completely resolved.
