Представлено клиническое наблюдение пациента с воротной холангиокарциномой. Пациенту был выполнен практически весь современный комплекс исследований, проведено дооперационное стадирование. Однако, сопутствующий холангит, труднодоступная анатомическая локализация и стелющийся характер роста искажали результаты инструментальных исследований. Истинный объем поражения был установлен интраоперационно, что привело к расширению объема  резекции печени.</p></abstract><trans-abstract xml:lang="en"><p>Klatskin’s tumor is  a  rare  malignant neoplasm characterized by  the  absence of  specific   symptoms, challenges in verification and  difficulties in assessing the  true extent  of the  tumor. We present a clinical case  of a patient with  hilar  cholangiocarcinoma. The  patient received  almost the  entire modern complex of  radiologic examinations  for  preoperative  staging.  However,   concominant  cholangitis, hard-to-reach anatomical localization and tumor’s  creeping-growth distorted the results of instrumental studies. The true volume of the lesion was detected only intraoperatively and resulted in an expansion of liver resection volume.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>воротная холангиокарцинома</kwd><kwd>опухоль Клацкина</kwd><kwd>холангит</kwd><kwd>резекция печени</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hilar cholangiocarcinoma</kwd><kwd>Klatskin’s tumor</kwd><kwd>cholangitis</kwd><kwd>liver resection</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">Dondossola D, Ghidini M, Grossi F, et al.
