Recent history of acute idiopathic pericarditis, presenting recurrent complaints of chest pain and elevated CRP values. Initial TTE showed minimal pericardial effusion. Axial T1-weighted image (A), short-axis T2-weighted image (B), LGE-image in vertical long-axis (C) and short-axis (D). Minimally thickened pericardial layers (2.5 mm thickness) with SI similar to that of myocardial tissue on T1-weighted imaging (arrowheads, A). High SI on T2-weighted imaging (arrowheads, B), and strong pericardial on LGE-imaging (arrowheads, C,D). No evidence of residual pericardial fluid.
