A 22-year-old male presented with chest pain 3 days after his second
dose of the COVID-19 vaccine. Cardiac magnetic resonance imaging
demonstrated myocardial and pericardial enhancement. Given imaging and
clinical findings, he was diagnosed with perimyocarditis. He was treated
with a multitude of medications including NSAIDs, colchicine, and
steroids. Fortunately, he was able to achieve symptom improvement. Due
to COVID-19 vaccination novelty, further research is needed to identify
side effects.
