Cardiac myocardial resonance imaging demonstrating late gadolinium enhancement of the basal to midanterior, anteroseptal, inferoseptal, and inferior segments and apical inferior segments of the left ventricle. Patchy enhancement within the septum on the side of the ventricle: (a) 2-chamber view (b) 3-chamber view (c) 4-chamber view, (d) short-axis view at the base, (e) short-axis view at the level of the papillary muscles, and (f) short-axis view at the level of the apex.

On cardiac magnetic resonance imaging, there was extensive, midwall patchy late gadolinium enhancement consistent with acute myocarditis (Figure 1).
Pathological slides from the endomyocardial biopsy: (a) damaged and normal myocardium, (b) normal myocardium, (c) multinucleated giant cells (H&E staining 20x), (d) multinucleated giant cells (H&E staining 40x), (e) mixed inflammatory cells, and (f) eosinophils.
