При МРТ в опухоли с бугристыми четко-нечеткими контурами превалировал средний изоинтенсивный сигнал на Т1ВИ и Т2ВИ с единичными мелкими оссификатами в толще опухоли, выявленными при РКТ.</p></sec><sec><title>Заключение</title><p>Заключение: Низкодифференцированная хордома имеет специфическую гистологическую и иммуногистохимическую картину, однако дифференциальная диагностика на основе методов лучевой визуализации в настоящее время является сложной задачей.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: Demonstrate a clinical case of poorly differentiated chordoma, confirmed using a wide range of research methods.</p></sec><sec><title>Material and methods</title><p>Material and methods: A 63-year-old female patient with poorly differentiated chordoma who underwent immunohistochemical examination, MRI, CT and scintigraphy.</p></sec><sec><title>Results</title><p>Results: An immunohistochemical study confirmed the morphological affiliation of the tumor, supplemented by the data of imaging methods.</p></sec><sec><title>Conclusion</title><p>Conclusion: The poorly differentiated type of chordoma has a specific immunohistochemical picture, however, differential diagnosis based on imaging methods is currently a difficult task.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>низкодифференцировая хордома</kwd><kwd>МРТ</kwd><kwd>КТ</kwd><kwd>остеосцинтиграфия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>poorly differentiated chordoma</kwd><kwd>MRI</kwd><kwd>CT</kwd><kwd>bone scan</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">Murphey MD, Andrews CL, Flemming DJ, et al.
