Case report of myocarditis in a 40-year-old, previously healthy man following the first dose of the mRNA
COVID-19 vaccine Comirnaty (BioNTech/Pfzer). Cardiac MRI on day 8 following admission revealed persistent myocardial inflammation throughout the left ventricle: myocardial hyper-intensities on T2w images indicating myocardial edema were detected in the left ventricle, primarily in the basal and mid inferoseptal and anterolateral segments as well as in the apical lateral segment. Diffuse late gadolinium enhancement was noted in the basal and mid anteroseptal and inferoseptal segments as well as in the apical septal segment. Approximately 90% of the total left ventricular mass was affected.
