Abstract:
:In the current and rapidly worsening pandemic, patients with COVID-19 may undergo imaging with FDG PET/CT. Because a significant proportion of infected patients may be asymptomatic, incidental discovery on a PET/CT scan performed for unrelated reasons can occur. Because of the highly infectious nature of this agent, it is important that interpreting physicians be aware of the typical imaging findings to identify potentially affected patients. We present the case of an asymptomatic patient referred for FDG PET/CT imaging of a lung nodule who demonstrated the typical CT findings of COVID-19 infection and was subsequently found to be positive on testing.
