On 2D transthoracic echocardiography, an incidental left atrial mass was seen, initially thought to be a thrombus predisposed by intermittent atrial fibrillation. Transoesophageal echocardiography confirmed that this left atrial mass originated from a fixed, non-homogenous, right superior pulmonary vein mass with an extracardiac extension. Because of this finding, a thorough search for a primary focus lead to the discovery of a contiguous posterior mediastinal mass, which was a round cell neoplasm on histology. Management was deemed palliative. Although rare, left-sided cardiac masses should prompt the physician to search for a malignancy in the lung in high-risk patients, as haematogenous spread via the pulmonary vein is a potential mechanism for spread.<\/jats:p>","DOI":"10.1136\/bcr-2016-218671","type":"journal-article","created":{"date-parts":[[2017,3,7]],"date-time":"2017-03-07T10:50:13Z","timestamp":1488883813000},"page":"bcr2016218671","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Pulmonary vein mass with extension to the left atrium diagnosed by echocardiography"],"prefix":"10.1136","volume":"2017","author":[{"given":"Jezreel Labrador","family":"Taquiso","sequence":"first","affiliation":[{"name":"Section of Cardiology, Department of Medicine, Philippine General Hospital, University of the Philippines Manila, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaime Alfonso Manalo","family":"Aherrera","sequence":"additional","affiliation":[{"name":"Section of Cardiology, Department of Medicine, Philippine General Hospital, University of the Philippines Manila, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose Donato","family":"Magno","sequence":"additional","affiliation":[{"name":"Section of Cardiology, Department of Medicine, Philippine General Hospital, University of the Philippines Manila, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric Oliver","family":"Sison","sequence":"additional","affiliation":[{"name":"Section of Cardiology, Department of Medicine, Philippine General Hospital, University of the Philippines Manila, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,3,7]]},"reference":[{"key":"2025082723482242000_2017.mar07_1.bcr2016218671.1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.3904\/kjim.2007.22.1.32","article-title":"Left atrium mass originating from pulmonary vein tumor","volume":"22","author":"Jeon","year":"2007","journal-title":"Korean J Intern Med"},{"key":"2025082723482242000_2017.mar07_1.bcr2016218671.2","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.68.7.4"},{"key":"2025082723482242000_2017.mar07_1.bcr2016218671.3","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-8703(03)00249-7"},{"key":"2025082723482242000_2017.mar07_1.bcr2016218671.4","first-page":"675","article-title":"Abstract: a 30-year analysis of cardiac neoplasms at autopsy","volume":"21","author":"Butany","year":"2005","journal-title":"Can J Cardiol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2016-218671","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T06:48:30Z","timestamp":1756363710000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2016-218671"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,3,7]]},"references-count":4,"alternative-id":["10.1136\/bcr-2016-218671"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2016-218671","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2017,3,7]]}}}
