The typical finding of hypereosinophilic syndrome (Eosinophilic myocarditis) in the delayed enhancement (DE) cardiac magnetic resonance (CMR) is the "double V" sign, which includes (a) normal myocardium, (b) thickened enhanced endomyocardial layer, and (c) overlying apical thrombus. Corticosteroids may result in significant improvement of myocardial involvement.
Keywords: cardiac magnetic resonance imaging; eosinophilic myocarditis; hypereosinophilic syndrome; loeffler endocarditis.
