В статье представлено клиническое наблюдение случайно выявленного объемного образования переднего средостения у 61-летней пациентки при плановом флюорографическом обследовании. Комплексная лучевая диагностика, включающая многослойную компьютерную томографию и магнитно-резонансную томографию органов грудной полости, позволила предположить эхинококковую природу кисты. Ключевыми диагностическими признаками послужили многокамерная структура образования, наличие обызвествлений в стенках и перегородках, а также отсутствие накопления контрастного вещества. Проведенное видеоторакоскопическое удаление кисты с последующим гистологическим исследованием подтвердило диагноз эхинококкоза. Данный клинический случай подчеркивает значимость применения мультимодальных лучевых методов для точной топической диагностики редких форм эхинококкоза и выбора оптимальной тактики лечения.</p></abstract><trans-abstract xml:lang="en"><p>A pericardial echinococcal cyst is a rare manifestation of hydatid echinococcosis, which can be diagnosed only through the use of advanced imaging techniques. The article describes a clinical case where a space occupying formation in the anterior mediastinum was discovered incidentally during a routine fluorographic examination in a 61-year-old patient. Comprehensive imaging diagnostics including thoracic computed tomography and magnetic resonance imaging suggested that the cyst had an echinococcal origin. The key diagnostic indicators were the multicameral structure of the formation, the presence of calcifications in the walls and septa, as well as the absence of contrast agent accumulation. Video-assisted thoracoscopic removal of the cyst followed by histological examination confirmed the diagnosis of echinococcosis. This case report highlights the importance of using multimodal imaging techniques for the precise diagnosis of rare forms of echinococcosis and selecting the optimal treatment strategy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эхиноккокоз</kwd><kwd>киста перикарда</kwd><kwd>компьютерная томография</kwd><kwd>магнитно-резонансная томография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>echinococcosis</kwd><kwd>pericardial cyst</kwd><kwd>computed tomography</kwd><kwd>magnetic resonance imaging</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">Ющук Н.Д., Венгеров Ю.Я.
