Цель работы: продемонстрировать возможности современной нейровизуализации в  идентификации ромбэнцефалосинапсиса и  обозначить основные маркеры дифференциального диагноза. В отделении лучевой диагностики ФГБУ РДКБ МЗ РФ мы наблюдали трех больных с  РЭС  — одну девочку и  двух мальчиков. Возраст пациентов составлял от  3 месяцев до  9 лет. Исследования выполнялись на магнитно-резонансном томографе Discovery 750 W компании GE с индукцией магнитного поля 3 Т. В результате исследования идентифицировали спектр диспластических изменений червя мозжечка, от его полного отсутствия до частичной аплазии с сохранением передней части. Кроме того, наблюдали 2 случая дисплазии мозжечка, мимикрирующей под РЭС. Благодаря высокому разрешению и отсутствию лучевой нагрузки высокопольная МРТ является предпочтительным диагностическим инструментом в определении и дифференциации редких аномалий структур ЗЧА у детей, в частности, такой спорадической патологии, как РЭС.</p></abstract><trans-abstract xml:lang="en"><p>Rombencephalosynapsys (RES) is a rare variant of anomalies of the posterior cranial fossa structures characterized by dysplastic fusion of cerebellar hemispheres and absence or hypoplasia of cerebellar vermis. Purpose: to demonstrate the possibilities of modern neuroimaging in the RES diagnosis and to identify the main markers of the differential diagnosis in posterior fossa structures (PFS) anomalies. In the department of Radiology of Russian Children’s Clinical Hospital, we observed 3 patients with RES (1 girl and 2 boys). Patients age varied from 3 months to 9 years. The studies were performed on high-field MR system GE Discovery 750 W 3 T. Results: оn MRI in patients with RES we identified the spectrum of dysplastic anomalies of the vermis, from complete absence to partial aplasia with preservation of its anterior part. Also, there were 2 case with cerebellar dysplastic features, resemling RES. The transcerebellar sulci were estimated as the a clue diagnostic marker of RES. Conclusion: High-field MRI is the preferred diagnostic tool in the definition and differentiation of the developmental anomalies of the PFC in the children, especially in patients with RES.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ромбэнцефалосинапсис</kwd><kwd>мозжечок</kwd><kwd>атаксия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rhombencephalosynapsis</kwd><kwd>cerebellum</kwd><kwd>ataxia</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">Ishak G.E., Dempsey J.C., Shaw D.W. et al.
