Thrombus in-situ has been associated with chronic pleural effusions, pulmonary resections, infections and other souces of chronic inflammation, it has not been described as occuring with rounded atelectasis. Herein, we present a rare case of a pulmonary artery thrombus in-situ adjacent to rounded atelectasis; this case underscores the necessity for careful assessment and advocates for heightened awareness of in-situ thrombus as a differential diagnosis when assessing for pulmonary embolisms.<\/jats:p>","DOI":"10.56305\/001c.127264","type":"journal-article","created":{"date-parts":[[2025,1,1]],"date-time":"2025-01-01T08:25:00Z","timestamp":1735719900000},"source":"Crossref","is-referenced-by-count":0,"title":["Rounded Atelectasis with In-Situ Thrombosis in Supplying Artery"],"prefix":"10.56305","volume":"4","author":[{"given":"Kyle","family":"Rollheiser","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05gq02987","id-type":"ROR","asserted-by":"publisher"}],"name":"Brown University","department":["Department of Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Hilario Brugu\u00e9s","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05gq02987","id-type":"ROR","asserted-by":"publisher"}],"name":"Brown University","department":["Department of Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeanna M.","family":"Harvey Barnes","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05gq02987","id-type":"ROR","asserted-by":"publisher"}],"name":"Brown University","department":["Department of Diagnostic Imaging"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0867-9877","authenticated-orcid":false,"given":"Terrance","family":"Healey","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05gq02987","id-type":"ROR","asserted-by":"publisher"}],"name":"Brown University","department":["Department of Diagnostic Imaging"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"35509","published-online":{"date-parts":[[2025,1,1]]},"reference":[{"issue":"5","key":"ref1","doi-asserted-by":"publisher","first-page":"689","DOI":"10.1148\/56.5.689","article-title":"Pulmonary Artery Thrombosis: Roentgen Manifestations","volume":"56","author":"J.
