Patients with MOE do not have specific signs and symptoms, and imaging may show cystic or solid masses. Therefore, it is often unclear preoperatively whether the mass is a benign or malignant ovarian tumor. This increases the possibility of salpingo-oophorectomy due to suspicion of malignancy which, in turn, affects the fertility of young women and alters their sex hormone levels. We report the case of a 14-year-old girl with three complete turns of torsion of both the right fallopian tube and right ovary, and enlargement of the right ovary without necrosis. We performed transumbilical laparoendoscopic single-site surgery (TU-LESS) for diagnosis and treatment. During surgery, an ovarian cyst was removed and sent for frozen section, revealing MOE. Fertility-sparing surgery was therefore performed and the affected ovary was suspended to prevent further torsion.<\/jats:p>","DOI":"10.3389\/fonc.2025.1475166","type":"journal-article","created":{"date-parts":[[2025,10,1]],"date-time":"2025-10-01T04:17:21Z","timestamp":1759292241000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Massive ovarian edema with fallopian tube torsion treated with transumbilical laparoendoscopic single-site surgery: a case report"],"prefix":"10.3389","volume":"15","author":[{"given":"Dan","family":"Mu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yangmei","family":"Shen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yali","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,10,1]]},"reference":[{"key":"B1","article-title":"Massive edema of the ovary simulating fibroma","volume":"34","author":"Kalstone","year":"1969","journal-title":"Obstetrics Gynecology"},{"key":"B2","article-title":"Massive edema of the ovary diagnosed with laparoscopic biopsy and frozen section","volume":"51","author":"Cepni","year":"2005","journal-title":"J Postgraduate Med"},{"key":"B3","doi-asserted-by":"publisher","first-page":"17","DOI":"10.3892\/mi.2021.17","article-title":"Massive ovarian edema with paraovarian cyst torsion treated with laparoscopic surgery: A case report","volume":"1","author":"Fukuda","year":"2021","journal-title":"Med Int"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-017-3782-4","article-title":"Multimodality imaging findings of massive ovarian edema in children","volume":"47","author":"Dahmoush","year":"2017","journal-title":"Pediatr Radiol"},{"key":"B5","article-title":"Massive ovarian edema in a menopausal woman.
