Ewing sarcoma is usually diagnosed in children. The peak incidence is registered in patients aged 10–15 years, whereas adults and children under 5 years of age are very unlikely to develop this disease. In this article, we also report a case of Ewing sarcoma of the skull bones affecting the sphenoid bone and sphenoid sinus. The patient has undergone surgery followed by chemoradiotherapy. High invasion potential (tumor spread in several directions), high malignancy, and compression of the adjacent structures of the brain make the analysis of Ewing sarcoma located in areas that cannot be easily approached particularly interesting for neurosurgeons, since surgery is the main treatment option for such patients.</p></abstract><trans-abstract xml:lang="ru"><p>В данной работе представлен ретроспективный анализ данных литературы, в которой описываются случаи развития саркомы Юинга в костях основания черепа крайне редкой локализации (в области клиновидной кости, ее крыльев, пазухи и близлежащих структур). Саркома Юинга чаще всего встречается в детском возрасте. Пик заболеваемости приходится на 10–15 лет. У взрослых и детей до 5 лет данная опухоль встречается крайне редко. Также в работе описано клиническое наблюдение за пациентом с саркомой Юинга костей черепа, поражающей клиновидные кость и пазуху. Было выполнено хирургическое удаление опухоли, а затем проведена химиолучевая терапия. В связи с распространенным характером роста опухоли (распространилась в нескольких направлениях), ее высокой злокачественностью, а также сдавлением прилежащих структур головного мозга изучение случаев возникновения саркомы Юинга в сложных для лечения анатомических зонах представляет большой интерес для нейрохирургии как основного метода лечения данного злокачественного новообразования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Ewing sarcoma</kwd><kwd>sphenoid bone</kwd><kwd>sella turcica</kwd><kwd>chiasmosellar region</kwd><kwd>endoscopic endonasal neurosurgery</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>саркома Юинга</kwd><kwd>клиновидная кость</kwd><kwd>турецкое седло</kwd><kwd>хиазмально-селлярная область</kwd><kwd>эндоскопическая эндоназальная нейрохирургия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Güzel A., Tatli M., Er U. et al.
