СТЕРЕОТАКСИЧЕСКОЕ РАДИОХИРУРГИЧЕСКОЕ ЛЕЧЕНИЕ СТЕБЕЛЬНОЙ КРАНИОФАРИНГИОМЫ НА АППАРАТЕ LEKSELL GAMMA KNIFE PERFEXION

Craniopharyngioma is a benign tumor of the brain, developing from the epithelial cells of craniopharyngeal duct, from which are formed abiogenetically the stem and rear part of the pituitary gland. The peculiarity of stem craniopharyngiomas is dense accretion of the tumor with arterial and neural structures of supra-para-retrosellar area, which makes surgical treatment technically difficult, and sometimes — obviously impossible. In the world literature at this point does not contain messages about the isolated stem radiosurgical treatment of craniopharyngiomas with application installations, Gamma knife or CyberKnife. A clinical case of stereotactic radiosurgical treatment in the mode of hypofractionation on the Leksell Gamma Knife Perfexion apparatus with a positive result in the form of a significant regression of visual disturbances is presented. Index terms: stereotactic radiosurgery, hypofractionation, craniopharyngioma, sellar region.
