Fetal MRI raised suspicion of arteriovenous malformation (AVM). The baby was delivered at 36 weeks via C-section, and initial brain MRI suggested a possible neoplastic lesion.<\/jats:p>\n               <jats:p>Cerebral angiography confirmed a large AVM involving the left choroid plexus with arterial feeders from the left anterior and posterior choroidal arteries and a large venous varix draining into the vein of Galen. Both arterial feeders were successfully embolised with Onyx and glue, achieving complete occlusion.<\/jats:p>\n               <jats:p>Choroid plexus AVMs are rare and often lead to intraventricular or intraparenchymal haemorrhage. Surgical treatment has shown success, but endovascular management is effective, especially for small, deep-seated AVMs, offering a better prognosis.<\/jats:p>","DOI":"10.1136\/bcr-2023-258254","type":"journal-article","created":{"date-parts":[[2024,1,10]],"date-time":"2024-01-10T03:45:18Z","timestamp":1704858318000},"page":"e258254","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Fetal choroid plexus arteriovenous malformation, masquerading as a neoplastic lesion"],"prefix":"10.1136","volume":"17","author":[{"given":"Afshan","family":"Shaikh","sequence":"first","affiliation":[{"name":"Ziauddin University, Karachi, Sindh, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7827-6854","authenticated-orcid":false,"given":"Anam","family":"Khan","sequence":"additional","affiliation":[{"name":"Aga Khan University, Karachi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Farwa","family":"Mohsin","sequence":"additional","affiliation":[{"name":"Aga Khan University, Karachi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tanveer Ul","family":"Haq","sequence":"additional","affiliation":[{"name":"Aga Khan University, Karachi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,1,9]]},"reference":[{"key":"2025082801313665000_17.1.e258254.1","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.16.17306"},{"key":"2025082801313665000_17.1.e258254.2","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1177\/197140090501800118","article-title":"Embolization of Choroid plexus Arteriovenous malformation: A case report","volume":"18","author":"Gupta","year":"2005","journal-title":"Rivista Di Neuroradiologia"},{"key":"2025082801313665000_17.1.e258254.3","doi-asserted-by":"crossref","first-page":"e121","DOI":"10.1016\/j.wneu.2019.08.145","article-title":"Primary Intraventricular hemorrhage in pediatric patients: causes, characteristics, and outcomes","volume":"133","author":"Guo","year":"2020","journal-title":"World Neurosurgery"},{"key":"2025082801313665000_17.1.e258254.4","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.119.025783"},{"key":"2025082801313665000_17.1.e258254.5","doi-asserted-by":"crossref","first-page":"e499","DOI":"10.1097\/SCS.0000000000005373","article-title":"Unusual Intraventricular tumor Mimicker; Choroid plexus Arteriovenous malformation","volume":"30","author":"Izgi","year":"2019","journal-title":"J Craniofac Surg"},{"key":"2025082801313665000_17.1.e258254.6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1673.1998.tb00568.x"},{"key":"2025082801313665000_17.1.e258254.7","doi-asserted-by":"crossref","first-page":"710","DOI":"10.1067\/mpd.2002.129033","article-title":"Choroid plexus Arteriovenous malformation presenting with Intraventricular hemorrhage","volume":"141","author":"Heck","year":"2002","journal-title":"J Pediatr"},{"key":"2025082801313665000_17.1.e258254.8","first-page":"283","article-title":"Radiosurgery of Choroidal and Cisternal cerebral Arteriovenous malformations","volume":"47","author":"Nataf","year":"2001","journal-title":"Neurochirurgie"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2023-258254","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T08:31:42Z","timestamp":1756369902000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2023-258254"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,1]]},"references-count":8,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2024,1,9]]},"published-print":{"date-parts":[[2024,1]]}},"alternative-id":["10.1136\/bcr-2023-258254"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2023-258254","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2024,1]]}}}
