В статье представлено описание клинического случая пациентки, обратившейся с жалобами на отечность верхнего века левого глаза и боль в периорбитальной и височной областях. Магнитно-резонансная и рентгеновская томографии головы показали внутрикостный мягкотканный очаг в области переднелатеральных отделов верхней стенки левой орбиты. Выполнено хирургическое удаление опухоли. По данным гистологического исследования ткань опухоли соответствовала эозинофильной гранулеме.</p></abstract><trans-abstract xml:lang="en"><p>Eosinophilic granuloma represents a subtype of histiocytosis, a benign tumor-like condition characterized by aberrant proliferation of antigenpresenting Langerhans cells derived from dendritic cells. This article presents a clinical case of a patient admitted with complaints of left upper eyelid edema and pain in the periorbital and temporal regions. Imaging studies revealed an intraosseous soft tissue lesion on the left side of the orbital roof. Surgical excision of the tumor was performed, and histological analysis of the biopsy specimen confirmed the diagnosis of eosinophilic granuloma.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эозинофильная гранулема</kwd><kwd>опухоль основания черепа</kwd><kwd>воспалительное заболевание центральной нервной системы</kwd><kwd>гистиоцитоз</kwd><kwd>гранулема орбиты</kwd><kwd>новообразование кости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>eosinophilic granuloma</kwd><kwd>skull base tumor</kwd><kwd>inflammatory disorder of central nervous system</kwd><kwd>hystiocytosis</kwd><kwd>orbital granuloma</kwd><kwd>bone neoplasm</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Юсупова Л.А., Юнусова Е.И., Гараева З.Ш., Мавлютова Г.И.
