Currently, thoracoscopic removal is considered to be the most preferred method of surgical treatment of these mass formations, in view of the least trauma, fewer complications, and a reduction in the time of postoperative recovery of patients. A clinical case of surgical treatment of a patient with a giant paravertebral tumor originating from the 4<sup>th</sup> thoracic root is presented. The tumor was an incidental finding during routine fluorography. There were no focal neurological symptoms. Taking into account the topographic and anatomical features of the volumetric formation, the patient underwent a combined two-stage surgical intervention, where the first stage was laminectomy and removal of the foraminal component of the tumor from the posterior approach, the second stage was single-port video-assisted thoracoscopic removal of the mediastinally located tumor fragment. The operation was performed under conditions of a collapsed lung on the side of the intervention. In the postoperative period, no neurological deficit was noted; according to the control introscopy, the tumor was removed completely. According to the results of histological examination – neurofibroma (Grade I).</p></abstract><trans-abstract xml:lang="ru"><p>Паравертебральные опухоли медиастинальной локализации — обширная группа патологических процессов с различной гистологической картиной и биологическим поведением, хирургическим лечением при которой занимаются врачи разных специальностей, таких как нейрохирурги и хирурги-онкологи. В настоящее время наиболее предпочтительным методом хирургического лечения данных объемных образований принято считать торакоскопическое удаление, ввиду наименьшей травматичности, меньшего количества осложнений и сокращения времени послеоперационного восстановления пациентов. Представлен клинический случай хирургического лечения пациентки с гигантской паравертебральной опухолью, исходящей из IV грудного корешка. Опухоль стала случайной находкой при выполнении плановой флюорографии. Очаговой неврологической симптоматики не отмечалось. Учитывая топографо-анатомические особенности объемного образования, пациентке было проведено комбинированное двуэтапное оперативное вмешательство: сначала выполняли ламинэктомию и удаление фораминального компонента опухоли из заднего доступа, затем одно портовое видеоассистированное торакоскопическое удаление медиастинально расположенного фрагмента опухоли. Операция проходила в условиях коллабированного легкого на стороне вмешательства. В послеоперационном периоде неврологического дефицита не отмечено, по данным контрольной интроскопии опухоль удалена тотально. По результатам гистологического исследования — нейрофиброма (Grade I). Приведенный клинический пример показывает успешную коллаборацию спинальных и торакальных хирургов, а также иллюстрирует возможности современной минимально инвазивной хирургии.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>paravertebral tumor</kwd><kwd>dumb-bell tumor</kwd><kwd>video-assisted toracoscopy</kwd><kwd>tumor resection</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>паравертебральная опухоль</kwd><kwd>опухоль по типу «песочных часов»</kwd><kwd>видеоассистированная торакоскопия</kwd><kwd>удаление опухоли</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was carried out within the framework of the state task on the topic: "Development of a minimally invasive system for continuous assessment of biomechanical properties of the craniospinal system of cerebrospinal fluid circulation and cortical perfusion".</funding-statement><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания по теме: «Разработка малоинвазивной системы непрерывной оценки биомеханических свойств краниоспинальной системы ликворообращения и корковой перфузии».</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Basankin IV, Naryzhnyi NV, Giulzatyan AA, Malakhov SB.
