Incidental Finding of COVID-19 Lung Infection in 18F-FDG PET/CT: What Should We Do?

We report the case of an asymptomatic (no fever, no cough, no dyspnea) 80-year-old woman who had an F-FDG PET/CT scan for initial staging of Lieberk�hnian adenocarcinoma located on anal canal. Chest analysis incidentally revealed bilateral diffuse patchy ground-glass opacity with mild increasing F-FDG uptake, consistent with incidental COVID-19 infection finding during the March 2020 pandemic. The infection was confirmed by reverse transcription-polymerase chain reaction. It led us to improve patient flow and to undertake broader measures to avoid patient clinical issues and potential disease spreading.
