We report two cases of COVID-19-associated organising pneumonia (OP) occurring beyond 4 weeks from the acute onset of symptoms. Both tested positive for SARS reverse transcription\u2013PCR 2\u2009months before presentation with a resolution of respiratory symptoms. The first case presented with residual fatigue and worsening exertional dyspnoea. Chest CT revealed an OP pattern. The second case presented with worsening cough and new-onset pleuritic chest pain with persistent radiological consolidation. A transbronchial lung biopsy confirmed OP. Both patients responded well to 12 weeks of steroid therapy. This case illustrates the rare presentation of OP as a late sequela of COVID-19 and the good response to steroid therapy.<\/jats:p>","DOI":"10.1136\/bcr-2021-246119","type":"journal-article","created":{"date-parts":[[2021,10,29]],"date-time":"2021-10-29T11:55:36Z","timestamp":1635508536000},"page":"e246119","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":19,"title":["Organising pneumonia manifesting as a late-phase complication of COVID-19"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0750-3087","authenticated-orcid":false,"given":"Boon Hau","family":"Ng","sequence":"first","affiliation":[{"name":"Respiratory Unit, Department of Medicine, Pusat Perubatan Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3788-4789","authenticated-orcid":false,"given":"Andrea Yu-Lin","family":"Ban","sequence":"additional","affiliation":[{"name":"Respiratory Unit, Department of Medicine, Pusat Perubatan Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3283-649X","authenticated-orcid":false,"given":"Nik Nuratiqah","family":"Nik Abeed","sequence":"additional","affiliation":[{"name":"Respiratory Unit, Department of Medicine, Pusat Perubatan Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7526-361X","authenticated-orcid":false,"given":"Mohamed","family":"Faisal","sequence":"additional","affiliation":[{"name":"Respiratory Unit, Department of Medicine, Pusat Perubatan Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,10,29]]},"reference":[{"key":"2025082801093047000_14.10.e246119.1","doi-asserted-by":"crossref","first-page":"103500","DOI":"10.1016\/j.ebiom.2021.103500","article-title":"SARS-CoV-2 activates lung epithelial cell proinflammatory signaling and leads to immune dysregulation in COVID-19 patients","volume":"70","author":"Chen","year":"2021","journal-title":"EBioMedicine"},{"key":"2025082801093047000_14.10.e246119.2","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(20)30086-4"},{"key":"2025082801093047000_14.10.e246119.3","doi-asserted-by":"publisher","DOI":"10.1136\/thoraxjnl-2020-216088"},{"key":"2025082801093047000_14.10.e246119.4","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.06.00013505"},{"key":"2025082801093047000_14.10.e246119.5","doi-asserted-by":"crossref","DOI":"10.1371\/journal.pone.0240347","article-title":"Organizing pneumonia of COVID-19: time-dependent evolution and outcome in CT findings","volume":"15","author":"Wang","year":"2020","journal-title":"PLoS One"},{"key":"2025082801093047000_14.10.e246119.6","doi-asserted-by":"publisher","DOI":"10.1055\/s-0032-1325157"},{"key":"2025082801093047000_14.10.e246119.7","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2020.17023"},{"key":"2025082801093047000_14.10.e246119.8","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa2021436"},{"key":"2025082801093047000_14.10.e246119.9","doi-asserted-by":"crossref","DOI":"10.1183\/13993003.02808-2020","article-title":"Intravenous methylprednisolone pulse as a treatment for hospitalised severe COVID-19 patients: results from a randomised controlled clinical trial","volume":"56","author":"Edalatifard","year":"2020","journal-title":"Eur Respir J"},{"key":"2025082801093047000_14.10.e246119.10","doi-asserted-by":"publisher","DOI":"10.1186\/s13054-020-03400-9"},{"key":"2025082801093047000_14.10.e246119.11","doi-asserted-by":"crossref","first-page":"377","DOI":"10.1016\/j.resinv.2020.12.005","article-title":"Sustained coronavirus disease 2019-related organizing pneumonia successfully treated with corticosteroid","volume":"59","author":"Takumida","year":"2021","journal-title":"Respir Investig"},{"key":"2025082801093047000_14.10.e246119.12","unstructured":"In-Gyu B , Kyung-Wook H , Jung Wook Y .
