Bilateral Lymphadenopathy After COVID Vaccine in 18F-Choline PET/MRI Performed for Hyperparathyroidism

Abstract We describe a case of a 56-year-old woman with primary hyperparathyroidism. 18 F-Choline PET/MRI revealed incidental bilateral axillary lymphadenopathy with mild-moderate increased 18 F-choline uptake. The patient had her first and third doses of COVID-19 vaccines from the left arm and second dose of vaccine from the right arm before PET examination.
