  Fig. 1. Transthoracic echocardiography showed dramatic improvement of left ventricle wall thickness and systolic motion after prednisolone treatment (10 mg) for 3 days. a Parasternal long axis view before treatment showed increased wall thickness of the septum and posterior wall (arrowheads). b Apical four chamber view before treatment showed increased wall thickness of the inferior septum, anterior lateral wall and apex (arrows). c Parasternal long axis view after treatment showed resolution of thickened wall of the septum and posterior wall (arrowheads). d Apical four chamber view after treatment showed resolution of the thickened inferior septum, anterior lateral wall and apex (arrows)

  Fig. 2. Endomyocardial biopsy specimen revealed myocarditis with increased eosinophils infiltration, consistent with eosinophilic myocarditis. a The specimen showed extensive inflammatory cell infiltration (arrowheads), composed of mononuclear lymphocytes and numerous eosinophils and some fibrosis (H&E stain, × 400). b The specimen showed diffuse eosinophils infiltration (arrows, H&E stain, × 1000)
