Investigation of cardiomyopathy using cardiac magnetic resonance imaging part 2: Rare phenotypes

Figure 6 A 38-year-old man presented with progressive shortness of breath. Serum measurements demonstrated hypereosinophilia. A: Horizontal long-axis SSFP sequence showing mild circumferential hypertrophy of the left ventricle (arrows) Note the normal thin right ventricular free wall (arrowheads), a useful differentiating feature from cardiac amyloid; B: Late-enhanced horizontal long-axis sequence showing extensive high signal in the typical subendocardial distribution (arrowheads) of eosinophilic myocardial infiltration. Cardiac amyloid is the principal other cardiomyopathy that mimics this late gadolinium enhancement appearance.
