Borderline ovarian tumours are similarly uncommon, with an incidence of approximately 0.002%\u20130.006%. The concurrent presence of a microperforate hymen and a borderline ovarian tumour is therefore exceedingly unique with no documented cases to date. In this report, we review the case of a nulliparous woman in her late 20s who initially presented with an inability to have penetrative intercourse. A subocclusive hymenal variant was noted on examination and further imaging work-up resulted in the incidental discovery of a large ovarian mass subsequently noted to be a borderline ovarian tumour. Herein, we review contemporary approaches to the diagnosis and management of both hymenal variants and borderline ovarian tumours, and discuss fertility-sparing strategies for young women diagnosed with ovarian neoplasms.<\/jats:p>","DOI":"10.1136\/bcr-2022-252017","type":"journal-article","created":{"date-parts":[[2022,11,1]],"date-time":"2022-11-01T10:57:54Z","timestamp":1667300274000},"page":"e252017","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of a microperforate hymen leading to the incidental diagnosis of a borderline ovarian tumour"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0313-7438","authenticated-orcid":false,"given":"Mariam","family":"Ayyash","sequence":"first","affiliation":[{"name":"Department of Women\u2019s Health, Obstetrics and Gynecology, Henry Ford Health System, Detroit, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Madison","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Women\u2019s Health, Obstetrics and Gynecology, Henry Ford Health System, Detroit, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miriana","family":"Hijaz","sequence":"additional","affiliation":[{"name":"Department of Women\u2019s Health, Division of Gynecologic Oncology, Henry Ford Health System, Detroit, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,11,1]]},"reference":[{"key":"2025082712325208000_15.11.e252017.1","doi-asserted-by":"crossref","first-page":"59","DOI":"10.4322\/acr.2014.030","article-title":"Microperforated hymen: a case of delayed diagnosis","volume":"4","author":"Ferrarini","year":"2014","journal-title":"Autops Case Rep"},{"key":"2025082712325208000_15.11.e252017.2","doi-asserted-by":"crossref","first-page":"97","DOI":"10.5005\/jp-journals-10032-1052","article-title":"A rare case report of microperforate hymen with difficulty in penetration","volume":"2","author":"Kumar","year":"2014","journal-title":"J Safoms"},{"key":"2025082712325208000_15.11.e252017.3","doi-asserted-by":"crossref","first-page":"287","DOI":"10.4236\/ojog.2012.23060","article-title":"pinhole) hymen and infertility: a rare case report","volume":"2","author":"G\u00fcven","year":"2012","journal-title":"Open J Obstet Gynecol"},{"key":"2025082712325208000_15.11.e252017.4","doi-asserted-by":"crossref","first-page":"1407","DOI":"10.1007\/s00431-013-2123-3","article-title":"Hymenal anomalies in twins--review of the literature and case report","volume":"173","author":"Watrowski","year":"2014","journal-title":"Eur J Pediatr"},{"key":"2025082712325208000_15.11.e252017.5","doi-asserted-by":"crossref","first-page":"95","DOI":"10.1016\/j.jpag.2006.01.006","article-title":"Microperforate hymen resulting in pelvic abscess","volume":"19","author":"Sanfilippo","year":"2006","journal-title":"J Pediatr Adolesc Gynecol"},{"key":"2025082712325208000_15.11.e252017.6","first-page":"278","article-title":"The transverse vaginal septum: a clinicopathologic evaluation","volume":"54","author":"Suidan","year":"1979","journal-title":"Obstet Gynecol"},{"key":"2025082712325208000_15.11.e252017.7","doi-asserted-by":"crossref","first-page":"749","DOI":"10.1016\/S0022-3468(82)80440-5","article-title":"Unilateral renal agenesis with hematometrocolpos: report of two cases","volume":"17","author":"Radhakrishnan","year":"1982","journal-title":"J Pediatr Surg"},{"key":"2025082712325208000_15.11.e252017.8","doi-asserted-by":"crossref","first-page":"1010","DOI":"10.2214\/ajr.132.6.1010","article-title":"Hematometra and hematocolpos: ultrasound findings","volume":"132","author":"Sailer","year":"1979","journal-title":"AJR Am J Roentgenol"},{"key":"2025082712325208000_15.11.e252017.9","first-page":"120","article-title":"Imperforate hymen with hematocolpometra combined with elevated CA125","volume":"110","author":"Kalmantis","year":"2009","journal-title":"Bratisl Lek Listy"},{"key":"2025082712325208000_15.11.e252017.10","unstructured":"Moore KL N , Persaud TVN , Torchia MG .
