Липоматоз нерва – редкое доброкачественное врожденное поражение периферических нервов, крайне редко локализующееся в стволе седалищного нерва, что может вызывать затруднения в дифференциальной диагностике. Дифференциальная диагностика проводится со злокачественными опухолями (липосаркомой, злокачественная опухоль оболочек периферических нервов), чтобы избежать необоснованно агрессивного лечения.</p></sec><sec><title>Заключение</title><p>Заключение. Представленный клинический случай акцентирует значимость интегративного подхода, базирующегося на мультидисциплинарном анализе клинических, морфологических данных и данных современных методов медицинской визуализации, для точной верификации редких опухолей периферических нервов нетипичной локализации.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To present a clinical case of atypically located nerve lipomatosis with traumatic injury in an adult patient’s medical history, and to demonstrate the current capabilities of ultrasound diagnostics in this pathology.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A retrospective analysis of the patient’s medical history treated at the Peking University Third Hospital (China) was conducted.</p></sec><sec><title>Results</title><p>Results. Nerve lipomatosis is a rare benign congenital peripheral nerve lesion. Involvement of the sciatic nerve trunk is exceptionally uncommon and may pose diagnostic challenges in differential diagnosis. Differential diagnostics is carried out with malignant neoplasms (liposarcoma, malignant neoplasm of the peripheral nerve sheaths) to avoid unjustifiably aggressive treatment.</p></sec><sec><title>Conclusion</title><p>Conclusion. The presented clinical case highlights the importance of an integrative approach based on a multidisciplinary analysis of clinical, morphological, and advanced medical imaging data for the accurate verification of rare peripheral nerve tumors with atypical localization.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>липоматоз нерва</kwd><kwd>ультразвуковое исследование</kwd><kwd>седалищный нерв</kwd><kwd>контрастное средство</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nerve lipomatosis</kwd><kwd>ultrasound examination</kwd><kwd>sciatic nerve</kwd><kwd>contrast agent</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was conducted without sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Al Ghamdi YH, Alawad SH, Karem F, Alsaadi MJ.
