Abstract

Incidental detection of coronavirus disease-2019 (COVID-19) related lung changes in 18F-FDG PET/CT of oncology patients have been increasingly reported. Most of the case reports/series stressed upon the retrospective diagnosis of COVID-19 with the help of 18F-FDG PET/CT lung findings. In this case report, we introduce a different aspect of COVID-19 related lung changes in 18F-FDG PET/CT, interfering with the evaluation of metastatic lung lesions in patients with renal cell carcinoma.
