This study investigates the long-term radiological and functional findings of previously hospitalized COVID-19 patients who had residual pulmonary involvement at 3\u20136-month follow-up.\nMethodology: This retrospective cohort study was an extended analysis of a previously published study, including patients with COVID-19 pneumonia hospitalized between June 2020 and March 2021. Residual lung involvement due to COVID-19 pneumonia was classified according to the presence of ground glass opacities, honeycombing, traction bronchiectasis, reticulations, and parenchymal bands.\nResults: 51 out of the 157 patients with abnormal chest findings in high-resolution computed tomography (HRCT) scans at 3\u20136-month follow-up were included. Mean age of the study population was 60.5 \u00b1 10.5 years; 35 subjects were male (68.6%). HRCT controls were obtained 25.7 \u00b1 6.36 months after the diagnosis. There was regression of predefined radiological involvement in 39 patients (76.5%), whereas 11 patients (21.6%) exhibited stable findings, and one patient had progressive lung involvement with a usual interstitial pneumonia pattern. Persistent residual parenchymal bands were found mostly in ICU-admitted patients (p = 0.04), and reticulations were seen in patients with a CT severity score &gt; 18 (p = 0.04).\nConclusions: In most patients with pulmonary sequelae, lesions showed improvement after 18 months, with complete resolution in about one third of patients after a 6-month follow-up. There was a correlation between initial severity and persistence of lung abnormalities.<\/jats:p>","DOI":"10.3855\/jidc.21215","type":"journal-article","created":{"date-parts":[[2026,4,14]],"date-time":"2026-04-14T18:24:48Z","timestamp":1776191088000},"page":"342-349","source":"Crossref","is-referenced-by-count":0,"title":["Long-term follow-up of hospitalized COVID-19 patients with interstitial lung involvement"],"prefix":"10.3855","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8884-0682","authenticated-orcid":false,"given":"\u00d6zer","family":"\u00d6zdemir","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00fclru","family":"Polat","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mine","family":"Gayaf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Filiz","family":"G\u00fcldaval","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Damla","family":"Ser\u00e7e Unat","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0638-5629","authenticated-orcid":false,"given":"Tar\u0131k","family":"\u015eim\u015fek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2222","published-online":{"date-parts":[[2026,3,31]]},"container-title":["The Journal of Infection in Developing Countries"],"original-title":[],"link":[{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/download\/21215\/3842","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/download\/21215\/3842","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,14]],"date-time":"2026-04-14T18:24:49Z","timestamp":1776191089000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/view\/21215"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,31]]},"references-count":0,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2026,3,31]]}},"URL":"https:\/\/doi.org\/10.3855\/jidc.21215","relation":{},"ISSN":["1972-2680"],"issn-type":[{"value":"1972-2680","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,3,31]]}}}
