Patient 1 Serial T-2 Weighted CMR Imaging

Comparison of serial T2-weighted cardiac magnetic resonance (CMR) images for patient 1. At time of diagnosis (month 0), CMR imaging demonstrated diffusely elevated T2 signal throughout the myocardium. After corticosteroid initiation, CMR imaging (months 4 and 8) showed resolution of elevated T2 signal. Sixteen months after initiation of mepolizumab and cessation of maintenance corticosteroids, T2-weighted CMR imaging (month 29) showed no evidence of myocardial inflammation or edema.
