It may result from infectious causes (tuberculosis and Epstein–Barr virus infection) as well as noninfectious etiologies (drug-induced liver injury and systemic diseases). Its diagnosis and management require a multidisciplinary approach. Four pediatric patients with granulomatous liver involvement underwent abdominal ultrasonography, computed tomography, magnetic resonance imaging, and liver trephine biopsy with subsequent histological and immunohistochemical examination. In addition, polymerase chain reaction and serological testing were performed to identify infectious agents. All patients demonstrated multiple focal hepatic lesions. In two of them, Epstein–Barr virus DNA was detected, and histological analysis confirmed granulomas composed of epithelioid cells and giant cells. Following biopsy and symptomatic therapy, a reduction in hepatic lesions was observed, with complete resolution documented after 3 months. Granulomatous hepatitis is frequently asymptomatic and requires comprehensive diagnostic evaluation, including liver biopsy. Treatment aimed at eliminating the underlying cause leads to a favorable outcome. Early diagnosis and timely therapy are essential to prevent progression to hepatic fibrosis and cirrhosis.</p></abstract><trans-abstract xml:lang="ru"><p>Гранулёматозное воспаление печени (гранулёматозный гепатит) — редкое заболевание, характеризующееся образованием гранулём в печени. Оно может быть вызвано инфекционными (туберкулёз, вирус Эпштейна–Барр) и неинфекционными (лекарственные поражения, системные заболевания) факторами. Диагностика и лечение требуют междисциплинарного подхода. Четырём пациентам с гранулёматозным поражением печени проведены ультразвуковое исследование, рентгеновская компьютерная томография, магнитно-резонансная томография органов брюшной полости, а также трепанобиопсия печени с гистологическим и иммуногистохимическим исследованием. Дополнительно выполнены полимеразная цепная реакция и серологические тесты для выявления инфекционных агентов. У всех пациентов обнаружены множественные очаги в печени. У двух из них зафиксирована ДНК вируса Эпштейна–Барр и гистологически подтверждено наличие гранулём с эпителиоидными и гигантскими клетками. После биопсии и симптоматического лечения отмечено уменьшение очагов в печени, а через 3 мес — их полное исчезновение. Гранулёматозный гепатит часто протекает бессимптомно и требует комплексной диагностики, включая биопсию печени. Лечение, направленное на устранение причины, приводит к благоприятному исходу. Ранняя диагностика и своевременная терапия предотвращают развитие фиброза и цирроза печени.</p></trans-abstract><kwd-group xml:lang="en"><kwd>granulomatous liver inflammation</kwd><kwd>hepatitis</kwd><kwd>granulomatosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гранулёматозное воспаление печени</kwd><kwd>гепатит</kwd><kwd>гранулёматоз</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Yukhacheva DV, Rodina YA, Laberko AL, et al.
