We report a 53-year-old male chronic smoker presenting with tinnitus and ear pain. A resected brain mass demonstrated metastatic carcinoma (TTF-1 positive, CK7 diffuse). 18F-FDG PET\/CT revealed a moderately 18F-FDG -avid left upper lobe pulmonary nodule and a small 18F-FDG -avid intraparotid lesion. Given the smoking history and imaging characteristics, Warthin tumour was favoured over metastasis. Lung biopsy confirmed moderately to poorly differentiated adenocarcinoma; parotid FNAC confirmed Warthin tumour. This case highlights the diagnostic pitfall of 18F-FDG -avid benign salivary lesions during lung cancer staging\n Keywords: 18F-FDG PET\/CT; Warthin Tumour; lung cancer; smoking<\/jats:p>","DOI":"10.47391\/jpma.26-66","type":"journal-article","created":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T19:54:04Z","timestamp":1784058844000},"page":"1382-1383","source":"Crossref","is-referenced-by-count":0,"title":["Coexistence of Lung Cancer and Warthin Tumour in a Smoker: Importance of Accurate Interpretation of 18F-FDG-Avid Parotid Lesions"],"prefix":"10.47391","volume":"76","author":[{"family":"Sharjeel Usmani","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Anjali Jain","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Khulood Al Riyami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Subash Kheruka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"26547","published-online":{"date-parts":[[2026,7,12]]},"container-title":["Journal of the Pakistan Medical Association"],"original-title":[],"link":[{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/download\/42327\/4988","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/download\/42327\/4988","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T19:54:05Z","timestamp":1784058845000},"score":1,"resource":{"primary":{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/view\/42327"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,12]]},"references-count":0,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2026,7,14]]}},"URL":"https:\/\/doi.org\/10.47391\/jpma.26-66","relation":{},"ISSN":["0030-9982"],"issn-type":[{"value":"0030-9982","type":"print"}],"subject":[],"published":{"date-parts":[[2026,7,12]]}}}
