An accessory cavitated uterine malformation (ACUM) is a rare congenital Mullerian anomaly where an accessory cavity with normal lining of endometrium is seen within the myometrium of a normally functioning uterus. We report a case of a late-adolescence (18\u201321 years) girl who came with complaints of severe progressive dysmenorrhoea and chronic pelvic pain for 2 years. Ultrasound misdiagnosed it as a non-communicating rudimentary horn. On laparoscopy, a definite diagnosis of ACUM was made, followed by laparoscopic excision. The defect was sutured. Postoperatively, the patient is on regular follow-up and is asymptomatic at present.<\/jats:p>\n               <jats:p>This report presents a rare case of ACUM. It is often confused with a non-communicating rudimentary horn, adenomyosis with cavity and degenerated fibroid. History and clinical examination may provide a clue but not contribute to the diagnosis; instead, MRI can provide the correct interpretation. Laparoscopic excision and suturing give symptom relief and a good fertility outcome.<\/jats:p>","DOI":"10.1136\/bcr-2025-266026","type":"journal-article","created":{"date-parts":[[2025,8,12]],"date-time":"2025-08-12T02:30:36Z","timestamp":1754965836000},"page":"e266026","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Successful laparoscopic management of accessory cavitated uterine malformation misdiagnosed as non-communicating rudimentary horn in an unmarried woman"],"prefix":"10.1136","volume":"18","author":[{"given":"Virupaksha","family":"Ajjammanavar","sequence":"first","affiliation":[{"name":"OBG, JSS Academy of Higher Education and Research, Mysuru, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-4510-3980","authenticated-orcid":false,"given":"Sowmya","family":"Koteshwara","sequence":"additional","affiliation":[{"name":"OBG, JSS Academy of Higher Education and Research, Mysuru, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kusuma","family":"Ranganath","sequence":"additional","affiliation":[{"name":"OBG, JSS Academy of Higher Education and Research, Mysuru, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jayashree","family":"S","sequence":"additional","affiliation":[{"name":"OBG, JSS Academy of Higher Education and Research, Mysuru, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2025,8,11]]},"reference":[{"key":"2025082723180969000_18.8.e266026.1","doi-asserted-by":"crossref","first-page":"1036","DOI":"10.1111\/aogs.14801","article-title":"Accessory cavitated uterine malformation (ACUM): A scoping review","volume":"103","author":"Timmerman","year":"2024","journal-title":"Acta Obstet Gynecol Scand"},{"key":"2025082723180969000_18.8.e266026.2","doi-asserted-by":"publisher","DOI":"10.1097\/AOG.0b013e3181f7e735"},{"key":"2025082723180969000_18.8.e266026.3","doi-asserted-by":"crossref","first-page":"821","DOI":"10.1002\/uog.22173","article-title":"Imaging in gynecological disease (21): clinical and ultrasound characteristics of accessory cavitated uterine malformations","volume":"57","author":"Naftalin","year":"2021","journal-title":"Ultrasound Obstet Gynecol"},{"key":"2025082723180969000_18.8.e266026.4","doi-asserted-by":"crossref","first-page":"716","DOI":"10.1016\/j.fertnstert.2006.03.019","article-title":"Cystic myometrial lesion in the uterus of an adolescent girl","volume":"86","author":"Fisseha","year":"2006","journal-title":"Fertil Steril"},{"key":"2025082723180969000_18.8.e266026.5","doi-asserted-by":"crossref","DOI":"10.1016\/j.crwh.2020.e00187","article-title":"Diagnosis and laparoscopic excision of accessory cavitated uterine mass in young women: Two case reports","volume":"26","author":"Supermaniam","year":"2020","journal-title":"Case Rep Womens Health"},{"key":"2025082723180969000_18.8.e266026.6","doi-asserted-by":"crossref","first-page":"19","DOI":"10.1002\/ccr3.3371","article-title":"The first ethanol sclerotherapy of an accessory cavitated uterine mass","volume":"9","author":"Merviel","year":"2021","journal-title":"Clin Case Rep"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2025-266026","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T06:18:16Z","timestamp":1756361896000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2025-266026"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8]]},"references-count":6,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2025,8,11]]},"published-print":{"date-parts":[[2025,8]]}},"alternative-id":["10.1136\/bcr-2025-266026"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2025-266026","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8]]}}}
