Первичный склерозирующий холангит (ПСХ) - хроническое прогрессирующее заболевание печени, которое характеризуется деструктивным воспалением и фиброзом в желчных протоках, что может привести к билиарным стриктурам, вторичному билиарному циррозу, портальной гипертензии и печеночной недостаточности. Холангиолитиаз встречается более чем в половине случаев при ПСХ, и может быть, как осложнением, так и причиной вторичного склерозирующего холангита, поддерживая воспаление в протоках и способствуя образованию конкрементов. Известны генетические мутации, способствующие развитию желчных камней у молодых пациентов, в том числе холелитиаз, ассоциированный с низким содержанием фосфолипидов. Несмотря на широкий спектр современных методов лучевой и эндоскопической диагностики, по-прежнему возникают трудности в проведении дифференциальной диагностики заболеваний желчных протоков. В данной статье представлено клиническое наблюдение пациента 39 лет с первичным склерозирующим холангитом, дислипидемией и множественными холангиолитами в желчном пузыре, внутри- и внепеченочных желчных протоках.</p></sec><sec><title>Заключение</title><p>Заключение. Представленное клиническое наблюдение показывает трудности в оценке патогенеза, выборе диагностической и лечебной тактики у пациентов с тяжелым внутрипеченочным литиазом, который может имитировать новообразование печени. Сочетание неинвазивных и эндоскопических методов: магнитно-резонансной томографии, магнитно-резонансной холангиопанкреатикографии, эндоскопической ретроградной холангиопанкреатографии и холангиоскопии оказывается наиболее эффективным как с диагностической, так и с лечебной точки зрения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: to highlight the challenges of diagnosing and treating a patient with severe intrahepatic cholangiolithiasis.</p></sec><sec><title>Key points</title><p>Key points. Primary sclerosing cholangitis is a chronic progressive liver disease characterized by destructive inflammation and fibrosis in the bile ducts, leading to biliary strictures, secondary biliary cirrhosis, portal hypertension and liver failure. Cholangiolithiasis occurs in more than half of cases of primary sclerosing cholangitis and can be both a complication and a cause of secondary sclerosing cholangitis, maintaining inflammation in the ducts and facilitating stone formation. Genetic mutations are known to contribute to the development of gallstones in young patients, including low phospholipid-associated cholelithiasis. Despite the wide range of modern methods of radiological and endoscopic diagnostics, there are still difficulties in differential diagnostics of bile duct diseases. This article presents a clinical case of a 39-year-old male patient with primary sclerosing cholangitis, dyslipidemia and multiple cholangioliths in the gallbladder, intraand extrahepatic bile ducts.</p></sec><sec><title>Conclusion</title><p>Conclusion. The presented clinical case demonstrates the difficulties in assessing pathogenesis, choosing diagnostic and therapeutic approaches in patients with severe intrahepatic lithiasis that may mimic hepatic neoplasm. Combination of non-invasive and endoscopic methods, such as magnetic resonance imaging, magnetic resonance cholangiopancreatography, endoscopic retrograde cholangiopancreatography, and cholangioscopy, appears to be the most effective both diagnostically and therapeutically.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>первичный склерозирующий холангит</kwd><kwd>холелитиаз</kwd><kwd>холангит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary sclerosing cholangitis</kwd><kwd>cholelithiasis</kwd><kwd>cholangitis</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">Dave M., Elmunzer B.J., Dwamena B.A., Higgins P.D.
