There have been case reports of symptomatic PCP in individuals with a normally functioning immune system with typical clinical features and radiologic findings of bilateral and diffuse interstitial opacities. However, PCP in immunocompetent individuals presenting with lung nodules had been rarely reported. We report a 53-year-old immunocompetent gentleman who presented with subacute cough, progressive shortness of breath and radiographic findings of multiple lung nodules with central cavitation. The diagnosis of PCP was made by detection of PCP DNA PCR in bronchoalveolar lavage sample following fibreoptic bronchoscopy. This case also highlights the atypical radiographic findings of multiple cavitating lung nodules as a presentation of PCP in an immunocompetent patient.<\/jats:p>","DOI":"10.1136\/bcr-2020-241061","type":"journal-article","created":{"date-parts":[[2021,4,27]],"date-time":"2021-04-27T12:13:11Z","timestamp":1619525591000},"page":"e241061","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Pneumocystis pneumonia causing cavitating lung nodules in an immunocompetent individual"],"prefix":"10.1136","volume":"14","author":[{"given":"Olutobi","family":"Ojuawo","sequence":"first","affiliation":[{"name":"Respiratory Medicine, Sandwell and West Birmingham Hospitals NHS Trust, Birmingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2036-0981","authenticated-orcid":false,"given":"Thidar","family":"Htwe","sequence":"additional","affiliation":[{"name":"Respiratory Medicine, Sandwell and West Birmingham Hospitals NHS Trust, Birmingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0524-9449","authenticated-orcid":false,"given":"Onn Shaun","family":"Thein","sequence":"additional","affiliation":[{"name":"Respiratory Medicine, Sandwell and West Birmingham Hospitals NHS Trust, Birmingham, UK"},{"name":"Respiratory Medicine, Queen Elizabeth Hospital Birmingham, Birmingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adeel","family":"Sahal","sequence":"additional","affiliation":[{"name":"Respiratory Medicine, Sandwell and West Birmingham Hospitals NHS Trust, Birmingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,4,27]]},"reference":[{"key":"2025082711110725000_14.4.e241061.1","doi-asserted-by":"crossref","DOI":"10.1186\/s13054-018-2221-8","article-title":"Clinical course, treatment and outcome of Pneumocystis pneumonia in immunocompromised adults: a retrospective analysis over 17 years","volume":"22","author":"Schmidt","year":"2018","journal-title":"Crit Care"},{"key":"2025082711110725000_14.4.e241061.2","article-title":"Pneumocystis jirovecii pneumonia in an Immunocompetent Japanese man: a case report and literature review","volume":"2019","author":"Ide","year":"2019","journal-title":"Case Rep Pulmonol"},{"key":"2025082711110725000_14.4.e241061.3","doi-asserted-by":"publisher","DOI":"10.4065\/71.1.5"},{"key":"2025082711110725000_14.4.e241061.4","doi-asserted-by":"crossref","first-page":"229","DOI":"10.1007\/s12281-010-0029-3","article-title":"Pneumocystis jirovecii pneumonia: current knowledge and outstanding public health issues","volume":"4","author":"Harris","year":"2010","journal-title":"Curr Fungal Infect Rep"},{"key":"2025082711110725000_14.4.e241061.5","first-page":"651","article-title":"Pneumocystis carinii pneumonia in patients with solid tumors and lymphomas: predisposing factors and outcome","volume":"25","author":"Barbounis","year":"2005","journal-title":"Anticancer Res"},{"key":"2025082711110725000_14.4.e241061.6","doi-asserted-by":"crossref","first-page":"221","DOI":"10.1016\/j.hlc.2011.10.006","article-title":"Unusual presentation of Pneumocystis pneumonia in an immunocompetent patient diagnosed by open lung biopsy","volume":"21","author":"Harris","year":"2012","journal-title":"Heart Lung Circ"},{"key":"2025082711110725000_14.4.e241061.7","doi-asserted-by":"crossref","first-page":"122","DOI":"10.4103\/1755-6783.162374","article-title":"Pneumocystis jirovecii pneumonia in an immunocompetent host","volume":"8","author":"Koshy","year":"2015","journal-title":"Ann Trop Med Public Health"},{"key":"2025082711110725000_14.4.e241061.8","doi-asserted-by":"crossref","first-page":"327","DOI":"10.1016\/j.reaurg.2010.04.002","article-title":"Pneumocystose pulmonaire en dehors de l\u2019infection \u00e0 VIH","volume":"19","author":"Roux","year":"2010","journal-title":"R\u00e9animation"},{"key":"2025082711110725000_14.4.e241061.9","doi-asserted-by":"publisher","DOI":"10.1016\/S1286-4579(01)01514-3"},{"key":"2025082711110725000_14.4.e241061.10","doi-asserted-by":"crossref","unstructured":"Eddens T , Kaloti A , Kolls JK .
