В литературе упоминается о нескольких специфических радиологических паттернах, встречающихся у PLNTY, которые при сопоставлении с результатами патоморфологического исследования могут быть полезны при дифференциальной диагностике с другими эпилептогенными опухолями. Мы сообщаем о некоторых особенностях радиологической картины у двух детей с фармакорезистентной эпилепсией, прошедших процедуру эпилептической хирургии с гистологической верификацией PLNTY. </p></abstract><trans-abstract xml:lang="en"><p>A new form of morphologically and molecularly distinguishable epileptogenic neoplasia with characteristic microscopic findings and a distinct DNA methylation signature as well as frequent genetic anomalies, was revealed in 2017; the tumor was called polymorphous low-grade neuroepithelial tumor of the young (PLNTY). Several specific radiological patterns found in PLNTY when compared with the results of a pathomorphological study being useful in differential diagnosis with other epileptogenic tumors were mentioned in certain papers. Our paper is devoted to some particulars of the radiological picture in two children with pharmacoresistant epilepsy who underwent epileptic surgery with histological verification of PLNTY.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиморфная нейроэпителиальная опухоль низкой степени злокачественности молодого возраста (PLNTY)</kwd><kwd>структурная эпилепсия</kwd><kwd>нейровизуализация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Polymorphous low-grade neuroepithelial tumor of the young (PLNTY)</kwd><kwd>structural epilepsy</kwd><kwd>neuroimaging</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">Slegers R.J., Blumcke I.
