При комплексном обследовании (компьютерная томография, магнитнорезонансная томография) патологические изменения выявлены не были. При проведении ПЭТ/КТ с 18F-холином выявлено патологическое накопление радиофармпрепарата в субкаринальном лимфоузле. После выполнения трансбронхиальной биопсии лимфоузла и гистологического исследования было подтверждено метастатическое поражение.Заключение: ПЭТ/КТ всего тела позволила выявить метастаз гепатоцеллюлярного рака редкой локализации при биохимическом рецидиве — в медиастинальном субкаринальном лимфоузле, при отсутствии иных проявлений заболевания. ПЭТ/КТ всего тела является методом выбора при подозрении на внепеченочную локализацию прогрессирования гепатоцеллюлярного рака.</p></abstract><trans-abstract xml:lang="en"><p>Purpose: Analysis of a clinical case of detection of metastatic lesions of the mediastinal subcarinal lymph node in a patient with hepatocellular liver cancer using positron emission tomography combined with computed tomography (PET/CT).Material and methods: A patient with moderately differentiated hepatocellular liver cancer after surgical treatment and targeted therapy revealed a biochemical relapse. Complex examination (computed tomography, magnetic resonance imaging) revealed no pathological changes. PET/CT revealed pathological accumulation of 18F-choline in the subcarinal lymph node. After performing transbronchial lymph node biopsy and histological examination metastatic lesion was confirmed.Conclusion: Whole body PET/CT scan revealed rare metastases of hepatocellular cancer in biochemical recurrence — in the mediastinal subcarinal lymph node, in the absence of other manifestations of the disease. Whole body PET/CT is the method of choice for suspected extrahepatic localization of hepatocellular carcinoma progression.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ПЭТ/КТ</kwd><kwd>гепатоцеллюлярный рак</kwd><kwd>метастазирование</kwd><kwd>18F-холин</kwd><kwd>18F-фтордезоксиглюкоза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>PET/CT</kwd><kwd>hepatocellular carcinoma</kwd><kwd>metastasis</kwd><kwd>18F-choline</kwd><kwd>18F-fluorodeoxyglucose</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">Bray F, Ferlay J, Soerjomataram I, et al.
