При дальнейшем исследовании, в том числе, с использованием расширенных протоколов МР-сканирования, таких как МР-спектрометрия, было выдвинуто предположение о возможном диффузном многоочаговом глиальном поражении, которое подтвердилось при последующем гистологическом и иммунно-гистохимическом исследовании. Комплексный подход в оценке динамических данных МРТ, клинической картины и применение расширенных протоколов МР-сканирования позволили более точно определить неопластический характер изменений вещества головного мозга.</p></abstract><trans-abstract xml:lang="en"><p>In this case report of a patient with verified oligodendroglioma with gliomatous growth pattern, at primary clinical and magnetic resonance (MR) diagnosis, the diagnosis of autoimmune encephalitis (AE) was proposed due to the presence of certain radiological patterns typically seen in AE. Further investigation, including advanced MR methods such as magnetic resonance spectrometry, suggested a possible diffuse multifocal glial involvement, which was further confirmed by histological and immunohistochemical examination. The comprehensive approach of evaluating dynamic MRI data, clinical presentation and the use of extended MRI protocols may assist in precise determination of neoplastic changes in the brain tissue.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>олигодендроглиома</kwd><kwd>аутоиммунный энцефалит</kwd><kwd>МРТ</kwd><kwd>глиоматоз</kwd><kwd>МР-спектрометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oligodendroglioma</kwd><kwd>autoimmune encephalitis</kwd><kwd>MRI</kwd><kwd>gliomatosis</kwd><kwd>MR-spectrometry</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">Sanson M, Napolitano M, Cartalat-Carel S.
