Several Aspergillus species produce oxalic acid that precipitates with tissue calcium, and resulting crystals can cause local tissue injury. We report a 19-year-old Moroccan female without known immunodeficiency or underlying lung disease who presented with a thin-walled cystic pulmonary lesion with air-fluid level, initially suspected to represent a hydatid cyst. Following surgical resection, histopathology revealed abundant calcium oxalate crystals, supporting the diagnosis of pulmonary aspergillosis with prominent bronchopulmonary oxalosis. Clinicians should consider aspergillosis when evaluating unexplained cystic lesions with identified calcium oxalate crystals.<\/jats:p>","DOI":"10.1093\/omcr\/omag096","type":"journal-article","created":{"date-parts":[[2026,5,5]],"date-time":"2026-05-05T11:27:50Z","timestamp":1777980470000},"source":"Crossref","is-referenced-by-count":0,"title":["Bronchopulmonary oxalosis revealing pulmonary aspergillosis in an immunocompetent patient: a case report"],"prefix":"10.1093","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8327-1508","authenticated-orcid":false,"given":"Soufiane","family":"Abdouh","sequence":"first","affiliation":[{"name":"Thoracic Surgery Department, Mohammed VI University Teaching Hospital , Agadir 80000 ,","place":["Morocco"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mouad","family":"Gourti","sequence":"additional","affiliation":[{"name":"Thoracic Surgery Department, Mohammed VI University Teaching Hospital , Agadir 80000 ,","place":["Morocco"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Imane","family":"Sellam","sequence":"additional","affiliation":[{"name":"Infectious Diseases Department, Mohammed VI University Teaching Hospital , Agadir 80000 ,","place":["Morocco"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohsine","family":"Makloul","sequence":"additional","affiliation":[{"name":"Thoracic Surgery Department, Mohammed VI University Teaching Hospital , Agadir 80000 ,","place":["Morocco"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"El Mehdi","family":"Maidi","sequence":"additional","affiliation":[{"name":"Thoracic Surgery Department, Mohammed VI University Teaching Hospital , Agadir 80000 ,","place":["Morocco"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,6,15]]},"reference":[{"key":"2026062707164286300_ref1","doi-asserted-by":"publisher","first-page":"003","DOI":"10.1055\/s-0043-1777259","article-title":"Aspergillus and the lung","volume":"45","author":"Janssens","year":"2024","journal-title":"Semin Respir Crit Care Med"},{"key":"2026062707164286300_ref2","doi-asserted-by":"publisher","first-page":"e1","DOI":"10.1093\/cid\/ciw326","article-title":"Practice guidelines for the diagnosis and Management of Aspergillosis: 2016 update by the Infectious Diseases Society of America","volume":"63","author":"Patterson","year":"2016","journal-title":"Clin Infect Dis"},{"key":"2026062707164286300_ref3","doi-asserted-by":"publisher","first-page":"E174","DOI":"10.3978\/j.issn.2072-1439.2013.08.45","article-title":"Calcium oxalate crystal deposition in a patient with Aspergilloma due to Aspergillus niger","volume":"5","author":"Oda","year":"2013","journal-title":"J Thorac Dis"},{"key":"2026062707164286300_ref4","first-page":"183","article-title":"Oxalosis caused by aspergilus infection","volume":"133","author":"Nime","year":"1973","journal-title":"Johns Hopkins Med J"},{"key":"2026062707164286300_ref5","doi-asserted-by":"publisher","first-page":"32","DOI":"10.1016\/j.mmcr.2015.01.003","article-title":"Calcium oxalate in the sputum may aid in the diagnosis of pulmonary aspergillosis: a report of two cases","volume":"8","author":"Maeno","year":"2015","journal-title":"Med Mycol Case Rep"},{"key":"2026062707164286300_ref6","first-page":"737","article-title":"Crystals occurring in pulmonary cytology specimens.
