Abstract
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused the ongoing global pandemic. It can manifest a wide range of complications depending upon the severity of infection and comorbidities of the patient. Vaccines are very important measure to provide protection against COVID-19. We report a case of 72-year-old female with past medical history of hypertension and diabetes mellitus who underwent imaging with positron emission tomography (PET) scan imaging for staging of her small cell urinary bladder cancer and was found to have hypermetabolic uptake in the deltoid muscle of the left shoulder and hypermetabolic left axillary and pectoral lymph nodes due to mRNA BNT-162b2 (Pfizer-BioNTech COVID-19 vaccine) vaccine administrated 3 days ago prior to PET scan.
