Abstract:
We present a case of increased FDG uptake in the lymph nodes after COVID-19 vaccine administration. Restaging PET/CT scan of a 70-year-old woman with a history of multiple relapsed Hodgkin lymphoma showed muscle activity in the left upper arm laterally, which is in the deep musculature of the left deltoid muscle. There was also increased activity in several normal-sized left axillary nodes as well. On further review of the patient's history, she had received her second shot of the Pfizer-BioNTech COVID-19 vaccine approximately 2 days before the restaging PET/CT scan.
