We report a case in which a cord-like segment of omentum wound once around the utero-ovarian ligament, forming a knot that caused right ovarian torsion in an 80-year-old woman. She presented with a progressively enlarging abdominal mass measuring 100\u2009\u00d7\u2009220\u00a0mm. Laparotomy revealed omental entanglement with 180-degree torsion of the right ovary. Release of the knot restored blood flow, after which right salpingo-oophorectomy and resection of the cord-like omentum were performed. Histopathologic examination confirmed ischemic changes in a pre-existing ovarian cyst consistent with torsion-induced ischemia. The patient was discharged on postoperative Day 23 and remained well at follow-up. This case indicates that a cord-like omentum can act as an extrinsic trigger of ovarian torsion via a novel mechanism, and that ovarian torsion can occur in elderly women despite its predilection for reproductive-age females.<\/jats:p>","DOI":"10.1093\/jscr\/rjag617","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T18:01:19Z","timestamp":1784656879000},"source":"Crossref","is-referenced-by-count":0,"title":["Cord-like omental entanglement causing right ovarian torsion in an octogenarian woman: a case report"],"prefix":"10.1093","volume":"2026","author":[{"given":"Takahiro","family":"Inoue","sequence":"first","affiliation":[{"name":"Department of Gastrointestinal Surgery, Sapporo Kojinkai Memorial Hospital , Kita 1-jo Nishi 15-chome, Nishi-ku, Sapporo, Hokkaido 063-0052 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyouichi","family":"Uemura","sequence":"additional","affiliation":[{"name":"Department of Surgery, Doukikai Tomakomai Hospital , 3-9-10 Shin-Nakano-cho, Tomakomai, Hokkaido 053-0006 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,7,21]]},"reference":[{"key":"2026072114011427800_ref1","doi-asserted-by":"publisher","first-page":"221","DOI":"10.1111\/tog.12985","article-title":"Ovarian torsion: a modern approach to management","volume":"27","author":"Bailey","year":"2025","journal-title":"Obstet Gynaecol"},{"key":"2026072114011427800_ref2","doi-asserted-by":"publisher","first-page":"e47693","DOI":"10.7759\/cureus.47693","article-title":"Challenging diagnosis and management of an ovarian cyst torsion in a postmenopausal woman: a case report","volume":"15","author":"Ali","year":"2023","journal-title":"Cureus"},{"key":"2026072114011427800_ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2023.108686","article-title":"Giant ovarian serous cyst and postmenopausal adnexal torsion: an unusual case report and literature review","volume":"110","author":"Benlghazi","year":"2023","journal-title":"Int J Surg Case Rep"},{"key":"2026072114011427800_ref4","first-page":"479","article-title":"Ovarian torsion in postmenopausal women and risk of malignancy","volume":"3","author":"Yousefi","year":"2015","journal-title":"J Midwifery Reprod Health"},{"key":"2026072114011427800_ref5","doi-asserted-by":"publisher","first-page":"204","DOI":"10.1016\/j.ijscr.2015.04.009","article-title":"Small bowel obstruction secondary to greater omental encircling band\u2014unusual case report","volume":"10","author":"Sinwar","year":"2015","journal-title":"Int J Surg Case Rep"},{"key":"2026072114011427800_ref6","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1186\/1757-1626-2-21","article-title":"Strangulated inguinal hernia due to an omental band adhesion within the hernial sac: a case report","volume":"2","author":"Nachimuthu","year":"2009","journal-title":"Cases J"},{"key":"2026072114011427800_ref7","doi-asserted-by":"publisher","first-page":"rjy210","DOI":"10.1093\/jscr\/rjy210","article-title":"Bifid omental band: an unusual cause of small bowel obstruction","volume":"2018","author":"Saha","year":"2018","journal-title":"J Surg Case Rep"}],"container-title":["Journal of Surgical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/7\/rjag617\/69711110\/rjag617.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/7\/rjag617\/69711110\/rjag617.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T18:01:20Z","timestamp":1784656880000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jscr\/article\/doi\/10.1093\/jscr\/rjag617\/8739341"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7]]},"references-count":7,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2026,7,4]]}},"URL":"https:\/\/doi.org\/10.1093\/jscr\/rjag617","relation":{},"ISSN":["2042-8812"],"issn-type":[{"value":"2042-8812","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026,7]]},"published":{"date-parts":[[2026,7]]},"article-number":"rjag617"}}
