The causes of IFTT vary widely, ranging from intrinsic abnormalities of the fallopian tube itself to extrinsic factors affecting the peritubal environment. Here, we report a case of IFTT concomitant with an adenomatoid tumor arising from the fallopian tube. A 49\u2010year\u2010old triparous patient presented with sudden\u2010onset lower abdominal pain. Imaging findings revealed a 3\u2010cm solid mass in the subserosal area of the left fallopian tube, and laparoscopy confirmed IFTT involving a dark red and solid mass. Histologically, an adenomatoid tumor was identified in the twisted fallopian tube. Adenomatoid tumors of the fallopian tube are typically small, asymptomatic, and identified incidentally during gynecologic surgeries or imaging; therefore, this tumor is an extremely rare cause of IFTT. Adenomatoid tumors in the fallopian tube, even those as small as 3\u2009cm, can result in torsion.<\/jats:p>","DOI":"10.1155\/crog\/7233415","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T05:45:34Z","timestamp":1777009534000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Isolated Fallopian Tube Torsion Concomitant With an Adenomatoid Tumor Arising From the Fallopian Tube: A Case Report"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-1278-965X","authenticated-orcid":false,"given":"Fumitaka","family":"Mukouyama","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1116-6885","authenticated-orcid":false,"given":"Hiroshi","family":"Ishikawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aki","family":"Kinoshita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariko","family":"Inoue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshinori","family":"Itsuka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yohei","family":"Hosokawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenichi","family":"Harigaya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun-Ichiro","family":"Ikeda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaori","family":"Koga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,4,23]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2024.02.050"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2024.110268"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/20.10.970"},{"key":"e_1_2_9_4_2","first-page":"342","article-title":"Coexistance of Tubal Ectopic Pregnancy and Adenomatoid Tumor","volume":"17","author":"Honor\u00e9 L.
