Here, we present a rare case of pulmonary sarcoma undetectable by PET.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>A 77-year-old woman who had worsening dyspnoea on effort for a month and progressive chest discomfort with nocturnal cough for a week presented to our hospital. Contrast-enhanced computed tomography (CT) demonstrated a massive filling defect in the left pulmonary artery (PA). Two major differential diagnoses were considered; pulmonary thromboembolism and tumour-like lesions. Positron emission tomography-computed tomography (PET-CT) revealed that there was no abnormal accumulation of 18F-FDG in the mass. However, even after effective anti-thrombotic treatment for 3 weeks, a follow-up CT showed no reduction at all in the size of the lesion in the pulmonary artery. Therefore, surgery for diagnostic therapeutic purposes was performed.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>The present case is informative because it supports the idea that being aware of PA angiosarcoma as a potential differential diagnosis of pulmonary thromboembolism is essential, particularly in cases of no evident peripheral venous thrombosis and a negative D-dimer test, even if neither heterogenous contrast enhancement in CT and magnetic resonance imaging nor accumulation of 18-FDG in PET-CT is evident.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytad140","type":"journal-article","created":{"date-parts":[[2023,4,26]],"date-time":"2023-04-26T23:24:30Z","timestamp":1682551470000},"source":"Crossref","is-referenced-by-count":3,"title":["A case report of pulmonary artery intimal sarcoma negative for 18F-FDG mimicking pulmonary thromboembolism"],"prefix":"10.1093","volume":"7","author":[{"given":"Takuma","family":"Koike","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Biology and Medicine, Juntendo University School of Medicine , 2-1-1 Hongo, Bunkyo-ku, Tokyo 113-8421 , Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7098-9406","authenticated-orcid":false,"given":"Hiroshi","family":"Iwata","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Biology and Medicine, Juntendo University School of Medicine , 2-1-1 Hongo, Bunkyo-ku, Tokyo 113-8421 , Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuniaki","family":"Hirose","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Biology and Medicine, Juntendo University School of Medicine , 2-1-1 Hongo, Bunkyo-ku, Tokyo 113-8421 , Japan"},{"name":"The Department of Cardiology, Koshigaya Municipal Hospital , 10-32, Higashikoshigaya, Koshigaya, Saitama 343-8577 , Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tohru","family":"Minamino","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Biology and Medicine, Juntendo University School of Medicine , 2-1-1 Hongo, Bunkyo-ku, Tokyo 113-8421 , Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,4,26]]},"reference":[{"key":"2023042810472730000_ytad140-B1","doi-asserted-by":"crossref","first-page":"983","DOI":"10.1016\/S1470-2045(10)70023-1","article-title":"Angiosarcoma","volume":"11","author":"Young","year":"2010","journal-title":"Lancet Oncol"},{"key":"2023042810472730000_ytad140-B2","doi-asserted-by":"crossref","first-page":"377","DOI":"10.1053\/j.sult.2011.06.001","article-title":"Imaging sarcomas of the great vessels and heart","volume":"32","author":"Bendel","year":"2011","journal-title":"Semin Ultrasound CT MR"},{"key":"2023042810472730000_ytad140-B3","doi-asserted-by":"crossref","first-page":"1761","DOI":"10.1002\/1097-0142(19930301)71:5<1761::AID-CNCR2820710510>3.0.CO;2-7","article-title":"Sarcomas of the great vessels.
