Cardiac MRI of patient C: (a) T2 map demonstrating increased T2 signal consistent with edema in epicardium of the apical lateral wall; (b) four-chamber view showing late gadolinium enhancement in the apical lateral wall; (c) ECV map showing increased signal consistent with edema in the midanterolateral segments; (d) short axis with late gadolinium enhancements in the midanterolateral segments.

He underwent cardiac MRI which showed a left ventricular ejection fraction of 56% and evidence of myocarditis with myocardial edema demonstrated on T2 mapping and myocardial injury with focal LGE in the basal inferior, mid- to distal lateral/inferolateral walls (Figure 1).

Patient D cardiac MRI: (a) T2 map demonstrating increased T2 signal consistent with edema in the epicardium of the apical lateral wall; (b-d) 3-chamber, 4-chamber, and apical short axis delayed images, respectively, demonstrating epicardial late gadolinium enhancement (LGE) corresponding to area of edema on T2 map.

Cardiac MRI was again consistent with myocarditis with LVEF of 56% and myocardial edema by T2 mapping and myocardial injury with focal LGE in the mid- to distal inferolateral and lateral walls (Figure 2).
