Повышение осведомленности врачей об этой болезни может способствовать своевременной его диагностике и проведению лечебных мероприятий.</p><p>Целью данной работы явилось представление клинического наблюдения молодой женщины, страдающей редким кистозным заболеванием легких. При первичном обращении в клинику у пациентки были выявлены выраженные клинико-рентгенологические и функциональные изменения бронхолегочной системы и заподозрена редкая патология. Вопрос установления окончательного диагноза в самые сжатые сроки был принципиален, т. к. при уточнении диагноза ЛАМ подразумевалась инициация патогенетической терапии ингибитором mTOR. До 2010 г. определенный диагноз ЛАМ устанавливался только посредством хирургической биопсии легочной ткани. Однако в настоящее время на практике наблюдается сдвиг диагностической концепции в сторону менее инвазивных методов, при использовании которых у большинства пациентов исключается необходимость хирургического вмешательства.</p><p>Заключение. Продемонстрирован алгоритм установления определенного диагноза (спорадического ЛАМ) без морфологического исследования легкого.</p></abstract><trans-abstract xml:lang="en"><p>Sporadic lymphangioleiomyomatosis (LAM) is an orphan disease that primarily affects women of childbearing age. Increasing awareness of this disease among physicians can contribute to its timely diagnosis and treatment.</p><p>The aim of this work was to present a case of a young woman with a rare cystic lung disease. At the first visit to the clinic, the patient showed pronounced clinical, radiological and functional changes in the bronchopulmonary system, and a rare pathology was suspected. Establishing the definitive diagnosis in the shortest possible time was essential because pathogenetic therapy with an mTOR inhibitor had to be initiated as soon as the diagnosis of LAM had been clarified. Until 2010, a definitive diagnosis of LAM was made only by surgical lung biopsy. However, there is currently a shift in practice toward less invasive diagnostic methods that eliminate the need for surgical intervention in most patients.</p><p>Conclusion. An algorithm for making a definitive diagnosis (sporadic LAM) without morphologic examination of the lung is demonstrated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лимфангиолейомиоматоз (ЛАМ)</kwd><kwd>ангиомиолипома</kwd><kwd>ингибитор mTOR</kwd><kwd>сиролимус</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lymphangioleiomyomatosis</kwd><kwd>LAM</kwd><kwd>angiomyolipomas</kwd><kwd>mTOR inhibitor</kwd><kwd>sirolimus</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование и публикация статьи проводились в отсутствие внешнего финансирования</funding-statement><funding-statement xml:lang="en">The authors declare that no external funding was provided for the study or publication</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Thway K., Fisher C.
