С 1955 г. в литературе описаны лишь 19 случаев ганглиона, расположенного в области запястья и ставшего причиной туннельной нейропатии локтевого нерва. В связи с крайней редкостью данной патологии приведено собственное клиническое наблюдение.</p></sec><sec><title>Результаты</title><p>Результаты. На основании анализа литературы описаны типы компрессии локтевого нерва в зависимости от индивидуальных вариантов его строения, определяющие клиническую картину ГКГ. Приведены данные о распространенности ГКГ среди пациентов разного пола и возраста. Рассмотрен патогенез заболевания и основные диагностические методы. В клинике нервных болезней Первого МГМУ им. И. М. Сеченова в 2016 г. находился на лечении пациент с ГКГ и вызванной им компрессионно-ишемической нейропатией локтевого нерва. По данным визуализации ганглион ладонной поверхности кисти на уровне крючковидной кости, оттесняющий медиально локтевой нерв и локтевую артерию. Выполнена микрохирургическая декомпрессия правого локтевого нерва на уровне канала Гюйона, удаление суставного ганглиона по классической методике. В послеоперационном периоде отмечался частичный регресс неврологических расстройств.</p></sec><sec><title>Заключение</title><p>Заключение. Для установления причины нейропатии локтевого нерва в канале Гюйона клинические и электрофизиологические данные должны дополняться ультразвуковым и/или магнитно-резонансным обследованием. Детальное обследование этих пациентов позволяет уточнить морфологическую природу поражения и выявить такое редкое поражение, как ганглион.</p></sec></abstract><trans-abstract xml:lang="en"><p>The study objective is to analyze the existing research literature devoted to this problem and to assess clinical characteristics and specific features of the diagnosis and rational neurosurgical treatment for ganglion cyst of Guyon’s canal (GCGC) that caused compression neuropathy of the ulnar nerve.</p><sec><title>Materials and methods</title><p>Materials and methods. Since 1955, researchers reported only 19 cases of ganglion cysts located in the wrist area and associated with tunnel neuropathy of the ulnar nerve. Since this condition is extremely rare, we present our own clinical observations.</p></sec><sec><title>Results</title><p>Results. Using the literature data, we described various types of ulnar nerve compression according to individual nerve characteristics determining clinical manifestations of GCGC. We analyzed the prevalence of GCGC among patients of various age and gender, disease pathogenesis, and main diagnostic methods. A patient with GCGC-associated compression ischemic neuropathy of the ulnar nerve was treated in the neurological clinic of the I. M. Sechenov First Moscow State Medical University in 2016. Using visualization tools, we found a ganglion cyst located on the palmar surface at the level of the hook-shaped bone. The cyst caused medial displacement of the ulnar nerve and ulnar artery. We performed microsurgical decompression of the right ulnar nerve at the level of Guyon’s canal and removed the articular ganglion cyst using a standard procedure. In the postoperative period, we observed partial regression of neurological disorders.</p></sec><sec><title>Conclusion</title><p>Conclusion. To identify the cause of ulnar nerve neuropathy in Guyon’s canal, a physician should consider both clinical and electrophysiological data and the results of ultrasound examination and/or magnetic resonance imaging. A detailed examination of these patients allows clarifying morphological characteristics of the lesion and identifying such a rare lesion as ganglion cyst.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ладонный ганглион</kwd><kwd>псевдоопухолевая киста</kwd><kwd>канал Гюйона</kwd><kwd>компрессионная нейропатия локтевого нерва</kwd></kwd-group><kwd-group xml:lang="en"><kwd>palmar ganglion cyst</kwd><kwd>pseudotumor</kwd><kwd>Guyon’s canal</kwd><kwd>compression neuropathy of the ulnar nerve</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">Wang B., Zhao Y., Lu A., Chen C.
