It is crucial to differentiate PVOD from PAH, as the initiation of pulmonary vasodilators in PVOD cases can lead to worsening symptoms. PVOD is characterised by widespread occlusion of the pulmonary veins due to fibrosis and intimal proliferation. Although systemic sclerosis (SSc) is a well-established risk factor for PAH, its association with PVOD is rare and often overlooked. This case involves a woman in her early 40s with limited cutaneous SSc who developed progressive dyspnoea. Initially diagnosed with PAH, her condition worsened after starting pulmonary vasodilators. This case highlights the importance of considering PVOD in SSc patients and the need for careful diagnostic and therapeutic strategies.<\/jats:p>","DOI":"10.1136\/bcr-2025-266231","type":"journal-article","created":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T17:15:21Z","timestamp":1756314921000},"page":"e266231","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Unmasking pulmonary veno-occlusive disease after vasodilator therapy in limited cutaneous systemic sclerosis"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4735-1103","authenticated-orcid":false,"given":"Nanditha","family":"Sidda","sequence":"first","affiliation":[{"name":"General Medicine, Kasturba Medical College Manipal, Manipal, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rama","family":"Bhat","sequence":"additional","affiliation":[{"name":"General Medicine, Kasturba Medical College Manipal, Manipal, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5926-5885","authenticated-orcid":false,"given":"Praveen","family":"Tirlangi","sequence":"additional","affiliation":[{"name":"Infectious Disease, Kasturba Medical College Manipal, Manipal, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5850-3217","authenticated-orcid":false,"given":"Vamsidhar Reddy","family":"Pulagam","sequence":"additional","affiliation":[{"name":"Cardiothoracic Radiology, Narayana Institute of Cardiac Sciences, Bengaluru, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2025,8,27]]},"reference":[{"key":"2025082710151366000_18.8.e266231.1","doi-asserted-by":"publisher","DOI":"10.1183\/16000617.0056-2017"},{"key":"2025082710151366000_18.8.e266231.2","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00106008"},{"key":"2025082710151366000_18.8.e266231.3","doi-asserted-by":"crossref","first-page":"1687","DOI":"10.1007\/s10067-020-04953-4","article-title":"Pulmonary veno-occlusive disease: a probably underdiagnosed cause of pulmonary hypertension in systemic sclerosis","volume":"39","author":"Duarte","year":"2020","journal-title":"Clin Rheumatol"},{"key":"2025082710151366000_18.8.e266231.4","doi-asserted-by":"publisher","DOI":"10.1183\/13993003.00026-2016"},{"key":"2025082710151366000_18.8.e266231.5","first-page":"1320","article-title":"Clinical, functional and hemodynamic trajectories in pulmonary veno-occlusive disease","volume":"159","author":"Boulate","year":"2021","journal-title":"Chest"},{"key":"2025082710151366000_18.8.e266231.6","doi-asserted-by":"crossref","first-page":"257","DOI":"10.1186\/s12890-019-1031-3","article-title":"Targeted therapy in pulmonary veno-occlusive disease: time for a rethink?","volume":"19","author":"Luo","year":"2019","journal-title":"BMC Pulm Med"},{"key":"2025082710151366000_18.8.e266231.7","doi-asserted-by":"crossref","first-page":"329","DOI":"10.1007\/s40256-023-00577-6","article-title":"Clinical and Hemodynamic Responses to Imatinib in Pulmonary Veno-Occlusive Disease\/Pulmonary Capillary Hemangiomatosis: A Retrospective Pilot Study of Five Cases and Review of the Literature","volume":"23","author":"Nakamura","year":"2023","journal-title":"Am J Cardiovasc Drugs"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2025-266231","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T17:15:22Z","timestamp":1756314922000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2025-266231"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8]]},"references-count":7,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2025,8,27]]},"published-print":{"date-parts":[[2025,8]]}},"alternative-id":["10.1136\/bcr-2025-266231"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2025-266231","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8]]}}}
