We report a 61\u2010year\u2010old man with asthma who presented with progressive exertional dyspnoea for 2\u2009months and worsening productive cough for 2\u2009weeks. Peripheral blood eosinophilia was 15% (1314\u2009cells\/\u03bcL), and chest computed tomography showed bilateral peripheral, upper\u2010lobe\u2010predominant opacities. Bronchoalveolar lavage (BAL) revealed marked neutrophil predominance (85%) with only 6% eosinophils. Empirical antibiotics produced no clinical or radiographic improvement. Because clinical and radiological suspicion for CEP remained high despite discordant BAL findings, surgical lung biopsy was performed, demonstrating prominent eosinophilic infiltration with an organizing pneumonia pattern, supporting a diagnosis of CEP. The patient responded well to systemic corticosteroids. This case highlights the role of surgical lung biopsy in suspected CEP with atypical BAL findings and illustrates that organizing pneumonia may occur within the histopathological spectrum of CEP.<\/jats:p>","DOI":"10.1002\/rcr2.70780","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T00:14:04Z","timestamp":1790813644000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Chronic Eosinophilic Pneumonia: A Diagnostic Challenge With Atypical Bronchoalveolar Lavage Findings and an Organizing Pneumonia Pattern"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-6211-3256","authenticated-orcid":false,"given":"Yang\u2010Tai","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Chest Medicine Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3554-6111","authenticated-orcid":false,"given":"Wei\u2010Fan","family":"Ou","sequence":"additional","affiliation":[{"name":"Department of Chest Medicine Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-2757-8577","authenticated-orcid":false,"given":"Sha\u2010Yen","family":"Liang","sequence":"additional","affiliation":[{"name":"Department of Radiology Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu\u2010Hsuan","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7477-1049","authenticated-orcid":false,"given":"Wan\u2010Ching","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming\u2010Cheng","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Chest Medicine Taichung Veterans General Hospital  Taichung Taiwan"},{"name":"Department of Critical Care Medicine Taichung Veterans General Hospital  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,30]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"crossref","first-page":"667","DOI":"10.1016\/j.ccm.2025.07.007","article-title":"Eosinophilic Lung Diseases","volume":"46","author":"Cottin V.","year":"2025","journal-title":"Clinics in Chest Medicine"},{"key":"e_1_2_11_3_1","doi-asserted-by":"crossref","first-page":"397","DOI":"10.2147\/TCRM.S157882","article-title":"Chronic Eosinophilic Pneumonia: Clinical Perspectives","volume":"15","author":"Crowe M.","year":"2019","journal-title":"Therapeutics and Clinical Risk Management"},{"key":"e_1_2_11_4_1","doi-asserted-by":"crossref","first-page":"1737","DOI":"10.1016\/j.jaip.2017.05.002","article-title":"Chronic Eosinophilic Pneumonia: A Diagnostic Challenge","volume":"5","author":"Turner J.","year":"2017","journal-title":"Journal of Allergy and Clinical Immunology.
