Case ReportsLung Scintigraphy Imaging Features in a Young Patient With COVID-19.
A 31-year-old man developed diarrhea, fatigue, and intermittent fever for 2 weeks. The past few days he had experienced increasing dyspnea and dry cough. Ambulatory reverse transcriptase-polymerase chain reaction testing was positive for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). ⋯ Ventilation SPECT showed reduced ventilation with central nuclide deposition, whereas perfusion SPECT was inconspicuous, excluding pulmonary embolism. However, the low-dose CT revealed bilateral ground-glass opacities as previously described in COVID-19. This case highlights the procedure and findings of V/Q scanning (without embolism) in COVID-19.

Case Reports68Ga-PSMA PET/CT With Incidental Finding of COVID-19 in an Asymptomatic Patient.
A 70-year-old man with prostate adenocarcinoma was diagnosed by transrectal biopsy, with Gleason of 4 + 5 and initial PSA of 225 ng/mL since March 2020. Ga-PSMA PET/CT was performed as part of initial staging. ⋯ Another finding was a moderate PSMA uptake in the both lung parenchymas associated with opacities in CT. The patient denied any symptoms of coronavirus disease and was referred to the emergency department for RT-PCR COVID-19, and the result was positive.

Images of COVID-19 Infection Cases in Asymptomatic or Paucisymptomatic Patients With Neoplastic Diseases on 18F-FDG PET/CT.
We describe the results of F-FDG PET/CT of 3 patients referred to our institution during the single day of Monday, March 23, 2020, for an initial assessment of cancer extension or for the therapeutic evaluation of chemotherapy of neoplastic pathology, with no obvious infectious or respiratory symptoms at the time of examination. A retrospective review of the recent clinical history of patients in association with the typical pulmonary images on CT scan suggested the diagnosis of COVID-19. The characteristic aspects of COVID-19 infection should be recognized on F-FDG PET/CT, even if patients are asymptomatic or minimally symptomatic.
