Electrocardiographic and imaging findings at admission and course of high-sensitive troponin T. (A) ECG showing diffuse concave ST-elevation (II, aVF, V3-6) and PQ-depression (II, aVF). (B) MRI showing pericardial effusion (asterisks) in the four-chamber view (late enhancement PSIR). (C) MRI showing pericardial enhancement (arrows) (axial T1 DIXON Water only, which is a fat-saturated, non-ECG-triggered). (D) Longitudinal evolution of the high-sensitive troponin T levels during the hospitalization (MRI done on day 3; i.e., troponin 501 ng/L).

An electrocardiogram (ECG) showed concave ST-elevation and PQ-segment depression in several ECG leads and not related to a single coronary artery (Figure 1A). A cardiac magnetic resonance imaging (MRI) performed 2 days after symptom onset confirmed pericardial effusion and showed a circumferential pericardial contrast enhancement compatible with pericarditis; the myocardium showed no late gadolinium enhancement and no edema (Figures 1B,C). After 13 days, he was discharged (Figure 1D).
