Initial bronchoalveolar lavage and transbronchial lung biopsy revealed only nonspecific findings. During a CT\u2010guided needle aspiration biopsy (CT\u2010NAB), real\u2010time imaging showed that GGO gradually moved and shifted with positional changes. Although PAP is not fully confirmed yet due to a lack of pathological findings, this case highlights several clinical suggestions for patients with atypical lung shadows, including those with suspicion of PAP. Further, this is the first report of lung shadow mobility during CT\u2010NAB, emphasising the need for further studies to elucidate the pathophysiology of lung shadows and improve diagnostic accuracy.<\/jats:p>","DOI":"10.1002\/rcr2.70139","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T06:25:14Z","timestamp":1741760714000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Position\u2010Dependent Lung Shadow Movement"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4050-3337","authenticated-orcid":false,"given":"Tomohiro","family":"Bando","sequence":"first","affiliation":[{"name":"Department of Respiratory Medicine Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yumiko","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wataru","family":"Koike","sequence":"additional","affiliation":[{"name":"Department of Radiology Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuko","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of Pathology Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadayoshi","family":"Hirano","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soei","family":"Gen","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsuaki","family":"Yagi","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daizo","family":"Yaguchi","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masato","family":"Shizu","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5600-806X","authenticated-orcid":false,"given":"Motoshi","family":"Ichikawa","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine Gifu Prefectural Tajimi Hospital  Tajimi Japan"},{"name":"Department of Infectious Diseases Gifu Prefectural Tajimi Hospital  Tajimi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,2,28]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.202112-2742SO"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1183\/20734735.0018-2020"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.2040-4603.2016.tb00698.x"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0034-5687(68)90007-8"},{"volume-title":"Ventilation\/Blood Flow and Gas Exchange","year":"1990","author":"West J.
