Despite broad antimicrobial therapy for presumed pneumonia, negative microbiologic studies including bronchoalveolar lavage, and a nondiagnostic transbronchial biopsy, serial computed tomography (CT) scans showed progressive right\u2010sided consolidation, pleural effusion and CT signs of pulmonary hypertension. A routine contrast\u2010enhanced CT revealed a filling defect in the right pulmonary artery (PA). Dedicated CT pulmonary angiography confirmed persistent unilateral PA obstruction; together with pulmonary hypertension and a lack of improvement despite anticoagulation, this raised concern for chronic thromboembolic disease and PA malignancy. Fluorodeoxyglucose positron emission tomography (FDG PET) CT demonstrated mildly heterogeneous FDG uptake (SUV\n                    <jats:sub>max<\/jats:sub>\n                    2.9) favouring thrombus, and endobronchial ultrasound\u2010guided transbronchial needle aspiration yielded necrotic thrombotic material. Pulmonary endarterectomy, performed after interval clinical worsening, confirmed a chronic organizing septic thrombus. Weeks later, haemorrhagic infarction caused massive haemoptysis requiring wedge resection of the lung. This case highlights a rare septic thrombus in a unilateral PA leading to pulmonary infarction in an immunocompromised host.\n                  <\/jats:p>","DOI":"10.1002\/rcr2.70778","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T00:00:26Z","timestamp":1790812826000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unilateral Pulmonary Artery Lesion in an Immunocompromised Patient"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-9290-8396","authenticated-orcid":false,"given":"Seunghoon","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Medicine, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3660-5728","authenticated-orcid":false,"given":"Kyung Soo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Radiology, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4338-131X","authenticated-orcid":false,"given":"Dong Young","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Radiology, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7784-5971","authenticated-orcid":false,"given":"Boram","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Pathology and Translational Genomics, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junghee","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong Seop","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5124-605X","authenticated-orcid":false,"given":"Sung\u2010A","family":"Chang","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Medicine, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3164-889X","authenticated-orcid":false,"given":"Sun Hye","family":"Shin","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Department of Medicine, Samsung Medical Center Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,30]]},"reference":[{"issue":"9","key":"e_1_2_11_2_1","doi-asserted-by":"crossref","first-page":"4991","DOI":"10.21037\/jtd-20-651","article-title":"Bronchoalveolar Lavage as a Diagnostic Procedure: A Review of Known Cellular and Molecular Findings in Various Lung Diseases","volume":"12","author":"Davidson K.
