Multiple investigations were performed, including a CT pulmonary angiogram (CTPA) that was initially felt to show imaging features consistent with a diagnosis of chronic thromboembolic disease (CTED). The patient was referred to a tertiary pulmonary hypertension centre and the possibility of pulmonary vasculitis was raised. Subsequent positron emission tomography (PET)-CT revealed imaging features supporting this diagnosis. The patient was treated with intravenous cyclophosphamide infusions, following which her symptoms improved. A repeat PET-CT 6 months after treatment showed resolution in pulmonary artery and mediastinal uptake, but persistence of pulmonary artery occlusions on a repeat CTPA. A final diagnosis of pulmonary vasculitis secondary to Beh\u00e7et\u2019s disease was made. This case report aims to raise awareness of the imaging features of CTED and its mimics.<\/jats:p>","DOI":"10.1136\/bcr-2018-228409","type":"journal-article","created":{"date-parts":[[2019,4,9]],"date-time":"2019-04-09T07:15:49Z","timestamp":1554794149000},"page":"e228409","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Pulmonary vasculitis mimicking chronic thromboembolic disease"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5507-7062","authenticated-orcid":false,"given":"Noor","family":"Ali","sequence":"first","affiliation":[{"name":"Radiology, Royal United Hospitals Bath NHS Foundation Trust, Bath, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lynsey","family":"Clarke","sequence":"additional","affiliation":[{"name":"North Bristol NHS Trust, Rheumatology, Bristol, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert Valentine","family":"MacKenzie Ross","sequence":"additional","affiliation":[{"name":"Radiology, Royal United Hospitals Bath NHS Foundation Trust, Bath, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Graham","family":"Robinson","sequence":"additional","affiliation":[{"name":"Radiology, Royal United Hospitals Bath NHS Foundation Trust, Bath, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,4,8]]},"reference":[{"key":"2025082803082241000_12.4.e228409.1","doi-asserted-by":"publisher","DOI":"10.1183\/16000617.0121-2016"},{"key":"2025082803082241000_12.4.e228409.2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehv317"},{"key":"2025082803082241000_12.4.e228409.3","doi-asserted-by":"publisher","DOI":"10.1378\/chest.12-1384"},{"key":"2025082803082241000_12.4.e228409.4","doi-asserted-by":"publisher","DOI":"10.1183\/16000617.00000915"},{"issue":"2","key":"2025082803082241000_12.4.e228409.5","doi-asserted-by":"crossref","first-page":"357","DOI":"10.1148\/rg.2018170046","article-title":"Approach to Pulmonary Hypertension: From CT to Clinical Diagnosis","volume":"38","author":"Aluja Jaramillo","year":"2018","journal-title":"Radiographics"},{"issue":"3","key":"2025082803082241000_12.4.e228409.6","doi-asserted-by":"crossref","first-page":"425-9","DOI":"10.4103\/2045-8932.87312","article-title":"Isolated large vessel pulmonary vasculitis as a cause of chronic obstruction of the pulmonary arteries","volume":"1","author":"Hagan","year":"2011","journal-title":"Pulm Circ"},{"key":"2025082803082241000_12.4.e228409.7","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1177\/2045894018765346","article-title":"Isolated large vessel pulmonary vasculitis leading to pulmonary artery aneurysm formation: a case report and literature review","volume":"8","author":"Moghaddam","year":"2018","journal-title":"Pulm Circ"},{"key":"2025082803082241000_12.4.e228409.8","doi-asserted-by":"publisher","DOI":"10.1016\/j.semarthrit.2014.10.003"},{"key":"2025082803082241000_12.4.e228409.9","doi-asserted-by":"crossref","first-page":"801","DOI":"10.1148\/rg.243035091","article-title":"Thoracic manifestations of Beh\u00e7et disease at CT","volume":"24","author":"Hiller","year":"2004","journal-title":"Radiographics"},{"key":"2025082803082241000_12.4.e228409.10","doi-asserted-by":"publisher","DOI":"10.1378\/chest.127.6.2243"},{"key":"2025082803082241000_12.4.e228409.11","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0b013e318242ff37"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2018-228409","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T10:08:26Z","timestamp":1756375706000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2018-228409"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,4]]},"references-count":11,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2019,4,8]]},"published-print":{"date-parts":[[2019,4]]}},"alternative-id":["10.1136\/bcr-2018-228409"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2018-228409","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,4]]}}}
