The first two cases were reported by Jakob Erdheim and William Chester in 1930. The etiology and disease incidence are unknown. One of the main components of this disorder is a chronic uncontrollable inflammation. In 2016 ECD was classified as histiocytic neoplasm by the World Health Organization and was categorized as “tumors of histiocytes and dendritic cells”. More than half of patients testing positive for the BRAF mutation. The final diagnosis is made on the basis of histological finding. There are radiological markers indicating a possible association with the disease. This is a specific, almost pathognomonic scintigraphic picture of the skeleton, “coated” aorta, “hairy” kidney patterns on computer tomography. There is a Erdheim–Chester Disease Global Alliance (ECDGA), which try to unite and provide with information about diagnostics and treatment of this rare disease both patients and doctors. Today, there are 571 registered patients and only one from Russia. We demonstrate three clinical cases of patients with newly diagnosed ECD and the role of nuclear medicine methods in assessing the prevalence of this disease.</p></abstract><trans-abstract xml:lang="ru"><p>Болезнь Эрдгейма–Честера (БЭЧ) – чрезвычайно редкое заболевание с неблагоприятным прогнозом. Первые 2 случая были описаны Якобом Эрдгеймом (Jakob Erdheim) и Вильямом Честером (William Chester) в 1930 г. В настоящее время этиология и частота заболевания остаются неизвестными. Хроническое неконтролируемое воспаление является основным компонентом заболевания. В 2016 г. БЭЧ была классифицирована Всемирной организацией здравоохранения как гистиоцитарное клональное заболевание и отнесена в рубрику «опухоли из гистиоцитов и дендритных клеток». Более половины пациентов с БЭЧ имеют мутацию в гене BRAF. Окончательный диагноз ставится на основе результатов гистологического исследования. Существуют радиологические критерии, указывающие на возможную ассоциацию с заболеванием. Это специфическая, почти патогномоничная сцинтиграфическая картина скелета, «обложенная» аорта и «волосатые» почки по данным компьютерной томографии. На сегодняшний день существует Глобальный альянс по изучению БЭЧ (Erdheim–Chester Disease Global Alliance, ECDGA), призванный объединить для решения проблемы диагностики и лечения заболевания как медицинских специалистов, так и пациентов, страдающих от этой патологии. В альянсе зарегистрирован 571 пациент с БЭЧ, 1 из которых из России.</p><p>В статье продемонстрированы случаи впервые выявленной БЭЧ у 3 пациенток и описана роль методов ядерной медицины в оценке распространенности данного заболевания. </p></trans-abstract><kwd-group xml:lang="en"><kwd>Erdheim–Chester disease</kwd><kwd>single-photon emission computed tomography combined with computed tomography</kwd><kwd>positron emission tomography combined with computed tomography</kwd><kwd>rare clinical case</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>болезнь Эрдгейма–Честера</kwd><kwd>однофотонная эмиссионная компьютерная томография</kwd><kwd>совмещенная с компьютерной томографией</kwd><kwd>позитронно-эмиссионная томография</kwd><kwd>совмещенная с компьютерной томографией</kwd><kwd>редкий клинический случай</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
