It is a heterogeneous infectious disease caused by a wide variety of microorganisms, resulting in diverse imaging manifestations and characteristic patterns of pulmonary distribution. Despite advances in microbiological diagnostics and imaging, the literature still lacks a comprehensive overview integrating the imaging characteristics of pneumonia with pathogen-specific features and host susceptibility. A structured literature search of PubMed, Scopus, and Web of Science was conducted for studies published between 2000 and 2026 focusing on key pathogen groups and their radiological patterns. The reviewed evidence indicates that pulmonary distribution is determined by a complex interplay between infection routes, lung anatomy and physiology, host defense mechanisms, patient-specific, and environmental exposures. Radiological patterns, including lobar, bronchopneumonic, interstitial, necrotizing, abscess-forming, and cavitating forms, may correlate with pathogen type, disease severity, and host vulnerability. This integrative approach emphasizes the importance of correlating imaging findings with clinical presentation and patient risk factors to support early etiological assessment and guide empirical therapy. Improved understanding of the determinants of pulmonary distribution may facilitate personalized management, rapid clinical decision-making in emergencies and hospital settings, and improved clinical outcomes.<\/jats:p>","DOI":"10.3390\/diagnostics16111605","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T08:06:26Z","timestamp":1779696386000},"page":"1605","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Host, Pathogen, and Pulmonary Anatomy in Pneumonia: An Integrated Imaging and Clinical Perspective"],"prefix":"10.3390","volume":"16","author":[{"given":"Teodora","family":"Biciusca","sequence":"first","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas J.","family":"Vogl","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liv","family":"Goedeking","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa Joy","family":"Juergens","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"H\u00f6hne","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna-Sophia","family":"Dietrich","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreea-Ioana","family":"Nica","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Gotta","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aynur","family":"G\u00f6kduman","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon S.","family":"Martin","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Goethe University Frankfurt, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-8409-5904","authenticated-orcid":false,"given":"Mara","family":"Balteanu","sequence":"additional","affiliation":[{"name":"Department of Pneumology, Faculty of Medicine, Titu Maiorescu University, 031593 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirela-Elena","family":"Popescu","sequence":"additional","affiliation":[{"name":"Doctoral School, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-4765-7413","authenticated-orcid":false,"given":"Sorina-Ionelia","family":"Stan","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Faculty of Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9451-6969","authenticated-orcid":false,"given":"Viorel","family":"Biciu\u0219c\u0103","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Faculty of Medicine, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Gon\u00e7alves-Pereira, J., Froes, F., Pereira, F.G., Diniz, A., Oliveira, H., and Mergulh\u00e3o, P.
