There are only a few reports of cranial migration of an intradural fragment of a sequestered disc herniation.</p><sec><title>Clinical case</title><p>Clinical case. A 51-year-old patient who had previously undergone two operations at L5–S1 and L4–L5 levels was admitted to the hospital with complaints of low back pain with radiation to both legs, numbness in the perineum and inner surface of the thighs, urinary retention, constipation. Magnetic resonance imaging revealed a 30 mm mass located at the level of the L3 vertebral body, within the dural sac and filling its entire transverse diameter. The cauda equina nerve roots were compressed. Surgery was performed: the herniated sequestrum (30×10×10 mm) was separated from the nerve roots fixed to it and removed. After surgery, sensation in the buttocks and inner thighs returned, and urinary urge appeared. Rehabilitation is ongoing.</p></sec><sec><title>Discussion</title><p>Discussion. In most cases, IHID is diagnosed intraoperatively. In the presented case, the genesis of the formation remained unclear before surgery, so a laminectomy approach was chosen, which allowed for extensive revision of the intradural space, thorough radiculolysis, and identification of the cranial migration of the sequestrated disc herniation. The only effective treatment for IHID is surgery.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Интрадуральная грыжа межпозвоночного диска (ИГМД) встречается крайне редко. Сообщения о краниальной миграции интрадурального фрагмента секвестрированной грыжи диска единичны.</p><sec><title>Описание случая</title><p>Описание случая. Пациент 51 года, перенесший ранее две операции на уровнях L5–S1 и L4–L5, госпитализирован с жалобами на боль в нижней части спины с иррадиацией в обе ноги, чувство онемения в промежности и по внутренней поверхности бедер, нарушение мочеиспускания по типу задержки, запор. По данным магнитно-резонансной томографии обнаружено объемное образование на уровне тела позвонка L3 протяженностью 30 мм, расположенное в полости дурального мешка и заполняющее весь его поперечник, корешки конского хвоста компримированы. Произведена операция: грыжевой секвестр (30×10×10 мм) отделен от фиксированных к нему корешков и удален. После операции восстановилась чувствительность в области ягодиц и внутренней поверхности бедер, появились позывы на мочеиспускание; проводится реабилитация.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. В большинстве случаев ИГМД диагностируется интраоперационно. В представленном случае генез образования до операции оставался неясен, поэтому в качестве доступа выбрана ламинэктомия, которая позволила провести широкую ревизию интрадурального пространства, тщательный радикулолиз и выявить краниальную миграцию секвестрированной грыжи диска. Единственным эффективным методом лечения ИГМД является хирургическое вмешательство.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>интрадуральная грыжа межпозвоночного диска</kwd><kwd>краниальная миграция грыжи диска</kwd><kwd>интраоперационное УЗ-сканирование</kwd><kwd>синдром конского хвоста</kwd><kwd>хирургическое лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intradural disc herniation</kwd><kwd>cranial migration of a disc herniation</kwd><kwd>intraoperative ultrasound</kwd><kwd>cauda equina syndrome</kwd><kwd>surgery</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">Loya V.K., Krishna Narayan T.V., Singh Dhillon C., Shashikant Pophale C.
