This study aims to clarify this aspect by analyzing patients who underwent FDG positron emission tomography\/computed tomography (PET\/CT) and quantifying tumor standardized uptake values (SUV). Medical records of 29 patients with fine needle aspiration (FNA)\u2010confirmed Warthin tumors who underwent FDG\u2010PET\/CT near the diagnosis of Warthin tumor were reviewed. Key parameters included cancer history, cytologic diagnosis of Warthin tumor, maximum SUV on FDG PET\/CT, and tumor localization. Among the cohort, 18 males and 11 females (average age: 67.9\u2009years) were included. Most patients had malignant neoplasms (lung, head and neck, breast, others). One patient had synchronous liver cancer. Three individuals had bilateral Warthin tumors, and three had bifocal tumors, resulting in 35 tumors for analysis. Tumors were located in the parotid gland (28) and vicinity (7). SUVmax for the Warthin tumors ranged from 3.6 to 26.8, with an average SUVmax of 10.1. Warthin tumors exhibit significant and variable FDG accumulation, exceeding expectations and mimicking high\u2010grade malignancies. Awareness of this phenomenon is crucial for accurate staging and timely management. In cases of positive FDG PET\/CT uptake in periparotid, perimandibular, and upper jugular areas, FNA is recommended to avoid misinterpretation or delays in management.<\/jats:p>","DOI":"10.1002\/dc.25255","type":"journal-article","created":{"date-parts":[[2023,11,24]],"date-time":"2023-11-24T00:15:58Z","timestamp":1700784958000},"page":"116-122","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Fine
