Cardiac magnetic resonance imaging (MRI) demonstrated extensive subepicardial and midwall late enhancement typical of myocarditis in the anterior, lateral, and inferior walls along with extensive fibrosis with normal LVEF (Figure 1).
MRI of the left leg showing patchy increased STIR signal in the muscles but predominately involving the gastrocnemius muscles.

Despite persistently normal skeletal muscle enzyme levels, an MRI of the lower legs was performed and this showed active myositis involving the gastrocnemius muscles bilaterally (Figure 2).
Cardiac MRI showing extensive epicardial and midwall fibrosis in the anterolateral, lateral, inferolateral, and inferior walls from base to apex.

Six months later, a repeat of the cardiac MRI demonstrated resolution of myocarditis along with persistent, stable, and extensive myocardial fibrosis and preserved LVEF (Figure 3).
