Cardiac MRI demonstrates a high intensity signal on black blood short-tau inversion recovery image(A, arrows) in a region of the base of the interventricular septum, 8 days after admission. The high signal intensity on black blood shorttau inversion recovery image disappeared(B, arrows) and late gadolinium enhancement of left ventricular myocardium including interventricular septum was not detected(C, arrows) at 8 months (7 months after discharge).
