case_images: Cardiac myocardial resonance imaging (cMRI) demonstrated patchy gadolinium delayed enhancement within the right and left ventricular myocardia and pericardial thickening with enhancement, consistent with myocarditis or infiltrative disease though without T2-weighted evidence of edema (Figure 2).
