Methods: Between March 2020 and September 2021, 3135 patients admitted to the nuclear medicine department were retrospectively analyzed. Our study involved the oncology patients with a history of contact, clinical and labora- tory findings and possible COVID-19 disease, whose radiological findings at PET/CT and CT were compatible with viral pneumonia and confirmed by PCR testing. Results: Lung imaging findings suspicious of SARS-Co V-2 infection were found in 78 of 3135 patients (2,48%) included. The most frequent finding was multiple ground glass opacities (GGOs). In our study, we found characteristic peripheral ground-glass opacities with high FDG activitiy with increased nodal FDG uptake in favor of reactive lymphadenitis in FDG-PET/CT. Conclusion: Chest CT is used in the initial diagnosis and monitoring of COVID-19 progression as well as in the evalu- ation of complications. Although PET imaging is not typically considered among the primary research methods for the diagnosis of lower respiratory tract infections, it has made a significant contribution to the incidental diagnosis of especially asymptomatic COVID-19 oncological caseseninfo:eu-repo/semantics/openAccessArticle5444144710.14744/ejmi.2021.1408505946
