Transthoracic echocardiography showed a large circumferential pericardial effusion without tamponade physiology (Fig. 1).
Three-chamber T2-weighted image of left ventricle (LV) and right ventricular outflow tract (RVOT) with T2-weighted TSE sequences: There was no significantly increased signal intensity in the T2-weighted images to suggest edema of active inflammation. The T2-weighted images made before contrast showed mildly increased signal in the septal and lateral free wall of the LV on 3-chamber view and in the mid to anteroapical LV wall in the 2-chamber view.

The imaging revealed no signs of active inflammation (Fig. 2), but it did show a small area of epicardial enhancement characteristic of prior myocarditis (Fig. 3).
