case_images: Cardiac MRI imaging at short axis from 6 days after onset (baseline), 6 weeks after onset (second MRI), and 19 weeks after onset (third MRI). Yellow arrows depict myocardial LGE. Native T1 values were within the normal range in the areas determined to be LGE positive. Black blood T2MI 2-lumen showed areas of high signal intensity in the posterior wall and apex of the left ventricle on initial examination (yellow mark) but there were no abnormal findings on subsequent examinations. LGE, late gadolinium enhancement; MRI, magnetic resonance imaging.

case_images: Increased signal from the basal to the middle and lateral inferior wall on black blood T2WI 2-lumen imaging and similarly increased signal in the apical region were also present (Fig. 1). Cardiac MRI after 6 and 19 weeks showed the presence of LGE mainly in the middle layer of the inferior wall; however, the contrasted area was reduced (Fig. 1).
