Delayed diagnosis of glioblastoma can have a negative impact on the prognosis of the disease, which is why there is a need to find approaches for its earlier detection.</p><p>   The aim of this paper is to analyze possible difficulties and errors in the differential diagnosis of autoimmune encephalitis (AE) and glioblastoma based on literature data and our own clinical observations.</p><p>   Features such as onset of the disease at a young age, subacute development of symptoms, response to immunosuppressive therapy and the MRI imaging of bilateral T2 hyperintense changes in the limbic areas are typical for AE, but do not exclude the diagnosis of a primary tumor of the central nervous system. Therefore, caution should be exercised regarding the likelihood of a primary brain tumor when patients of any age group present with symptoms characteristic of AE, especially if no specific for AE antibodies are detected. To shorten the time to diagnosis, a multidisciplinary approach, critical analysis of clinical data, a shortening of the examination interval and an increase in the frequency of imaging follow-up examinations are required.</p></abstract><trans-abstract xml:lang="ru"><p>   Глиальные опухоли височной и парагиппокампальной локализации на ранних морфологических стадиях развития могут имитировать клиническую и нейровизуализационную картину лимбического энцефалита. Отсроченная диагностика глиобластомы может негативно отразиться на прогнозе заболевания, что обусловливает актуальность поиска подходов к ее более раннему распознаванию.</p><p>   Целью настоящей работы является анализ возможных трудностей и ошибок при дифференциальной диагностике аутоиммунных энцефалитов (АЭ) и глиобластом на основании данных литературы и собственных клинических наблюдений.</p><p>   Такие характеристики, как дебют заболевания в молодом возрасте, подострое развитие симптоматики, ответ на иммуносупрессивную терапию, МР-картина двусторонних Т2-гиперинтенсивных изменений лимбических областей, наиболее типичны для АЭ, однако не исключают диагноза первичной опухоли центральной нервной системы. Поэтому настороженность относительно вероятности первичного новообразования головного мозга целесообразна при развитии характерной для АЭ симптоматики у пациентов любых возрастных групп, особенно в отсутствие обнаружения специфичных для АЭ антител. Для минимизации сроков постановки диагноза необходимы мультидисциплинарный подход, критический анализ клинических данных, сокращение интервала и увеличение кратности выполнения контрольных нейровизуализационных исследований.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аутоиммунный энцефалит</kwd><kwd>лимбический энцефалит</kwd><kwd>глиома</kwd><kwd>глиобластома</kwd><kwd>дифференциальная диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>autoimmune encephalitis</kwd><kwd>limbic encephalitis</kwd><kwd>glioma</kwd><kwd>glioblastoma</kwd><kwd>differential diagnosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The investigation has not been sponsored</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">Graus F, Vogrig A, Muniz-Castrillo S, et al.
