Case ReportsIncidental 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 Lieberkühnian 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.

Case ReportsFDG PET/CT in Diagnosing COVID-19 Infection in a Cancer Patient With Exposure History But Minimal Symptoms.
A 56-year-old woman with high-grade neuroendocrine small cell carcinoma had known contact history of COVID-19 about 16 days prior to the restaging PET/CT. The patient was instructed to self-quarantine for 14 days, and no COVID-19 test was performed. ⋯ The FDG PET/CT images revealed new multifocal hypermetabolic bilateral pulmonary ground-glass opacities that are suggestive of COVID-19 pneumonia. Meanwhile, the patient's symptoms worsened, and a blood test later confirmed COVID-19 infection.

Case ReportsIncidental COVID-19 Pneumonia on 18F-Fluorocholine PET/CT.
We present the case of a patient who underwent F-fluorocholine PET/CT for biochemical recurrence of prostate cancer in which bilateral pneumonia was diagnosed. In the current state of COVID-19 pandemic, a high prevalence of incidental pneumonia may be expected, even with previous clinical triage, explained by a nondefined number of patients who were asymptomatic or minimally symptomatic for infectious process. Therefore, nuclear medicine physicians should be prepared to recognize and diagnose incidental COVID-19 pneumonia manifestation on F-fluorocholine PET/CT, due to the crucial epidemiological implications.

Case ReportsIncidental Discovery of a COVID-19 Infection on a Reevaluation FDG PET/CT in a Patient Treated for Hodgkin Lymphoma.
We report the results of F-FDG PET/CT in an asymptomatic case of COVID-19 infection. A 27-year-old woman underwent FDG PET/CT for revaluation of a stage IIIE B Hodgkin lymphoma after the fourth cycle of chemotherapy. ⋯ The patient who was initially asymptomatic was admitted for fever 28 hours after the PET/CT. The nasopharyngeal swab was positive for COVID-19, and the outcome was favorable.

Case Reports18F-FDG PET/CT in Hodgkin Lymphoma With Unsuspected COVID-19.
We present an asymptomatic 70-year-old man referred for an F-FDG PET/CT for initial staging of a Hodgkin lymphoma. F-FDG PET/CT showed bilateral cervical lymphadenopathy (stage II). Incidentally, the CT demonstrated bilateral ground-glass opacities with low-grade F-FDG activity. ⋯ The COVID-19 reverse transcriptase polymerase chain reaction (RT-PCR) examination result was negative. Given the high clinical suspicion for COVID-19, the patient was isolated and repeat RT-PCR was positive at 72 hours. RT-PCR may be falsely negative in early COVID-19 disease, even with positive CT findings.
