The adnexa are particularly rare sites for the formation of such malformations. Here, we present the case of a middle-aged woman who presented with spontaneous massive haemoperitoneum occurring as a result of a ruptured adnexal AVM. The diagnosis was suspected on transabdominal sonography and confirmed on CT angiography. The patient was shifted to the interventional radiology suite for an urgent angioembolisation following which she improved haemodynamically and her symptoms resolved. The case highlights the fact that although exceedingly rare, gonadal AVMs are an important cause of spontaneous intraperitoneal bleeding. Diagnostic and interventional radiology play an important role in the early and accurate diagnosis of this entity, and angioembolisation can be lifesaving in such patients.<\/jats:p>","DOI":"10.1136\/bcr-2023-254554","type":"journal-article","created":{"date-parts":[[2023,12,6]],"date-time":"2023-12-06T12:51:07Z","timestamp":1701867067000},"page":"e254554","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Adnexal arteriovenous malformation presenting with spontaneous massive haemoperitoneum"],"prefix":"10.1136","volume":"16","author":[{"given":"Sreedhara B","family":"Chaluvashetty","sequence":"first","affiliation":[{"name":"Radiodiagnosis and Imaging, Postgraduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6307-3085","authenticated-orcid":false,"given":"Prabhjyot Singh","family":"Chowhan","sequence":"additional","affiliation":[{"name":"Radiodiagnosis and Imaging, Postgraduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajan Mani","family":"Bhandari","sequence":"additional","affiliation":[{"name":"Radiodiagnosis and Imaging, Postgraduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jimil","family":"Shah","sequence":"additional","affiliation":[{"name":"Gastroenterology, Postgraduate Institute of Medical Education and Research, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2023,12,6]]},"reference":[{"key":"2025082801083880000_16.12.e254554.1","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1016\/j.suc.2013.10.006","article-title":"Spontaneous hemoperitoneum","volume":"94","author":"Kasotakis","year":"2014","journal-title":"Surg Clin North Am"},{"key":"2025082801083880000_16.12.e254554.2","doi-asserted-by":"crossref","unstructured":"Assimacopoulos A , Mehta TI , Brockmeier C , et al .
