Placental histology was normal (non-molar) and unusually, she developed ovarian hyperstimulation syndrome (OHSS) 4\u2009weeks later. She was managed conservatively following multidisciplinary team input to exclude malignant pathology. The rarity of late-onset spontaneous OHSS could have resulted in inappropriate surgical management. In the absence of supportive treatment there is also a risk of the condition progressing to a critical stage. Follow-up ultrasonography after termination of pregnancy should be considered for women with evidence of ovarian hyperstimulation, particularly if other risk factors for OHSS are present. Delayed-onset OHSS should be considered in women presenting with bilateral cystic ovarian enlargement after triploid pregnancy.<\/jats:p>","DOI":"10.1136\/bcr-2020-236950","type":"journal-article","created":{"date-parts":[[2020,10,31]],"date-time":"2020-10-31T16:40:22Z","timestamp":1604162422000},"page":"e236950","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Maternal complications of fetal triploidy: a case report"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1012-6910","authenticated-orcid":false,"given":"Sarah","family":"Wali","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynaecology, Imperial College Healthcare NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marianne","family":"Wild","sequence":"additional","affiliation":[{"name":"Department of Obstetrics & Gynaecology, Homerton University Hospital NHS Foundation Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,10,31]]},"reference":[{"key":"2025082707171609000_13.10.e236950.1","doi-asserted-by":"publisher","DOI":"10.1159\/000264259"},{"key":"2025082707171609000_13.10.e236950.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0029-7844(97)00540-1"},{"key":"2025082707171609000_13.10.e236950.3","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/13.8.2082"},{"key":"2025082707171609000_13.10.e236950.4","unstructured":"Kaloo PD , Louden KA , Khazali S .
