It is important to recognise these situations early and intervene quickly to attain the best outcome. We describe the case of a 45-year-old woman with a long-standing history of migraines with aura who presented to the emergency department with left-sided weakness and slurred speech. Work-up was unclear and she was diagnosed with cryptogenic stroke. Follow-up transoesophageal echocardiogram was suggestive of an atrial septal defect, though no clear defect was evident. Pulmonary angiography revealed an isolated PAVM arising from the right lower lung segmental artery with a 2\u2009mm feeding artery leading into 3\u20134\u2009mm of dysplastic vessel that connects to the vein. The vessel was embolised successfully using a combination of a 4\u2009mm Amplatzer Vascular Plug in the distal feeding artery and a 4\u2009mm Nester coil proximally.<\/jats:p>","DOI":"10.1136\/bcr-2017-221000","type":"journal-article","created":{"date-parts":[[2017,10,10]],"date-time":"2017-10-10T11:00:15Z","timestamp":1507633215000},"page":"bcr-2017-221000","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Stroke resulting from an isolated pulmonary arteriovenous malformation"],"prefix":"10.1136","volume":"2017","author":[{"given":"Jakob","family":"Saidman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hossam","family":"Abdou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sridhar","family":"Sampath Kumar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,10,10]]},"reference":[{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.1","first-page":"232470961663719","article-title":"Implications of an Incidental pulmonary arteriovenous malformation","volume":"4","author":"Holden","year":"2016","journal-title":"J Investig Med High Impact Case Rep"},{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.2","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201407-1254CI"},{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.3","doi-asserted-by":"publisher","DOI":"10.2169\/internalmedicine.51.7305"},{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.4","first-page":"73","article-title":"An isolated fistula between the right pulmonary artery and the right pulmonary vein: an unusual cause of stroke in a young female","volume":"18","author":"Husain","year":"2011","journal-title":"Cardiol J"},{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.5","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1016\/j.jocn.2016.01.006","article-title":"Isolated asymptomatic pulmonary arteriovenous malformation presenting with ischaemic stroke","volume":"29","author":"Bertram","year":"2016","journal-title":"J Clin Neurosci"},{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.6","doi-asserted-by":"crossref","first-page":"157","DOI":"10.2147\/VHRM.S53203","article-title":"Strokes in young adults: epidemiology and prevention","volume":"11","author":"Smajlovi\u0107","year":"2015","journal-title":"Vasc Health Risk Manag"},{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.7","first-page":"320","article-title":"Isolated pulmonary arteriovenous fistulas with massive right-to-left shunt as a rare cause of cryptogenic stroke in a young woman","volume":"16","author":"Dubrava","year":"2014","journal-title":"Isr Med Assoc J"},{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.8","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.55.7.959"},{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.9","first-page":"428","article-title":"A small pulmonary arteriovenous malformation as a cause of recurrent brain embolism","volume":"25","author":"Todo","year":"2004","journal-title":"AJNR Am J Neuroradiol"},{"key":"2025042712502181000_2017.oct09_2.bcr-2017-221000.10","first-page":"311","article-title":"Isolated pulmonary arteriovenous fistula without Rendu-Osler-Weber disease as a cause of cryptogenic stroke","volume":"75","author":"Kimura","year":"2004","journal-title":"J Neurol Neurosurg Psychiatry"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2017-221000","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T19:50:28Z","timestamp":1745783428000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2017-221000"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,10,10]]},"references-count":10,"alternative-id":["10.1136\/bcr-2017-221000"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2017-221000","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2017,10,10]]}}}
