Из анамнеза известно, что впервые уплотнение в подкожно-жировой клетчатке промежности выявлено в 2021 году по месту жительства. До 2024 г. за медицинской помощью пациентка не обращалась. По данным магнитно-резонансной томографии (МРТ) органов малого таза с внутривенным усилением от 19.03.2024 года визуализирована опухоль в ишиоанальной клетчатке слева размерами 6.0 × 5.1 × 9.0 см. Выполнено хирургическое вмешательство в объеме удаления новообразования.</p></sec><sec><title>ОБСУЖДЕНИЕ</title><p>ОБСУЖДЕНИЕ: шваннома (неврилеммома) — это доброкачественная опухоль миелиновой оболочки периферического нерва, состоящая из веретеновидных (шванновских) клеток. Изолированные шванномы при отсутствии генерализованного нейрофиброматоза встречаются лишь в 5% случаев выявления доброкачественных опухолей перианальной области. Поскольку неврилеммомы обычно проявляются в виде бессимптомных образований в промежности за исключением случаев обращения к врачу с симптомами сдавления окружающих органов и структур, предоперационная диагностика заболевания затруднена. В свою очередь, окончательный диагноз доброкачественной шванномы может быть установлен лишь на основании результатов гистологического исследования удаленного препарата.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: предпочтительным методом лечения и верификации доброкачественных неврилеммом является полное их удаление, поскольку при резекции они имеют тенденцию к продолженному росту. Удаление части опухоли является вариантом выбора в тех случаях, когда иссечение новообразования единым блоком может привести к повреждению близлежащих структур замыкательного аппарата прямой кишки (ЗАПК) — наружного анального сфинктера, мышцы, поднимающей задний проход, а также стенок прямой кишки, влагалища и мочеиспускательного канала.</p></sec></abstract><trans-abstract xml:lang="en"><p>Schwannoma (also known as neurilemmoma) is a type of benign tumor that originates from the myelin sheath around of peripheral nerves. It is composed of schwann cells, which are specialized cells that help to insulate nerve fibers. Schwannomas are relatively rare, accounting for only 5% of all benign tumors in the perineal region. They are usually asymptomatic and are only detected when they come into contact with other organs or structures, causing symptoms such as compression. Preoperative diagnosis of schwannoma is challenging, as it is often difficult to distinguish it from other types of tumors in the same area. The final diagnosis can only be confirmed by intraoperative histology.</p><p>The method of choice for benign neurilemmomas is complete removal, as they continue growth after resection. Removing part of the tumor may be an option in cases where removing the neoplasm en bloc could damage adjacent structures, such as anal sphincter, levators, rectum, vagina and urethra.</p><p>Clinical case: twenty-five years old female, had complaints of a tumor in the left buttock area and discomfort in a sitting position for 3 years. Pelvic MRI with intravenous contrast revealed a tumor 6.0 × 5.1 × 9.0 cm in the left ischial region. Surgical removal of the tumor was performed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>шваннома</kwd><kwd>неврилеммома</kwd><kwd>промежность</kwd><kwd>перианальная область</kwd></kwd-group><kwd-group xml:lang="en"><kwd>schwannoma</kwd><kwd>neurilemmoma</kwd><kwd>perineum</kwd><kwd>perianal area</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">Verocay J.
