Late Gadolinium Enhancement after COVID-19 Vaccination

Images in a 16-year-old female patient with chest pain 2 days after the second dose of COVID-19 vaccine and with a peak high -sensitivity cardiac troponin T level of 3492 pg/mL who underwent cardiac MRI 6 weeks after hospitalization. (A) Black-blood T2-weighted MR image in short-axis view shows no hyperintense signal to suggest myocardial edema. (B???D) Phase-sensitive inver-sion-recovery late gadolinium enhancement (LGE) MR images in (B) four-chamber and (C, D) short-axis planes show prominent subepicardial LGE involving more than 50% of the myocardium in the basal inferolateral and inferior segments of the left ventricle (arrows, C) and in the anterolateral (arrows, B and D), inferolateral, and inferior segments of the left ventricle at the midventricular level (arrows, D).
