Сниженные концентрации церулоплазмина и α-1-антитрпсина в сыворотке крови затрудняли диагностический поиск, что могло привести к неверным терапевтическим решениям. Однако результаты методов визуализации позволили установить первопричину поражения печени и ее цирротической трансформации. Аневризмы сосудов системы воротной вены - весьма редкая патология, и ее следует учитывать в дифференциально-диагностическом алгоритме при исключении других, более очевидных причин патологии печени.</p></abstract><trans-abstract xml:lang="en"><p>The authors presented their own clinical observation of an aneurysm of the left portal vein branch in a teenager with a long-term asymptomatic course. Reduced serum concentrations of ceruloplasmin and α-1-antitrpsin made diagnostic search difficult, which could lead to incorrect therapeutic decisions. However, the results of imaging methods allowed us to establish the root cause of liver damage and its cirrhotic transformation. Vascular aneurysms of the portal vein system are a very rare pathology, and it should be taken into account in the differential diagnostic algorithm while excluding other, more obvious causes of liver pathology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аневризма воротной вены</kwd><kwd>цирроз печени</kwd><kwd>визуализация</kwd><kwd>дифференциальная диагностика</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>portal vein aneurysm</kwd><kwd>liver cirrhosis</kwd><kwd>visualization</kwd><kwd>differential diagnosis</kwd><kwd>children</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">Kurtcehajic A., Zerem E., Alibegovic E., Kunosic S., Hujdurovic A., Fejzic J.
