Abstract:
A 75-year-old man underwent a positron emission tomography/computed tomography (PET/CT) scan with fluorine-18-prostate specific membrane antigen ([¹⁸F]F-PSMA-1007) for initial staging of prostate adenocarcinoma. The scan showed lung infiltrates predominantly in both lower lobes with moderate uptake, in addition to a bilateral pulmonary hilar lymph node uptake. CT images revealed ground-glass opacities and a reticular pattern, suggesting COVID-19 pneumonia, which was confirmed by reverse transcription polymerase chain reaction (RT-PCR). Similar incidental findings have been reported in patients undergoing PET/CT scans with other radiotracers. In this case, the probable lung angiogenesis linked to COVID-19 infection can be potencially demonstrated by [¹⁸F]F-PSMA-1007, which helps ensure timely diagnosis and appropriate care for cancer patients.
