Abstract

Purpose: The aim of this case series is to illustrate possible [18F]-FDG uptake patterns associated to COVID-19. Methods: Retrospective assessment of all Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scans performed for any clinical / oncological reason from 1st April 2020 to 30th April 2020. Results of PCR testing for SARS-CoV-2 were retrieved for all patients with lung consolidations and/or peripheral ground glass opacities characterized by increased metabolism to evaluate any possible association with the viral infection. Results: Seven (4%) out of 172 FDG-PET scans were included. Six out of seven patients (85%) had positive RT-PCR for SARS-CoV-2, while one patient (15%) had possible (not PCR confirmed) COVID-19 pneumonia. Conclusion: Suspicious accidental COVID-19 findings in Nuclear Medicine Department need to be reported and appropriately evaluated to implement proper supportive treatment and infection control measures.
