case_images: Cardiac magnetic resonance imaging images (four-chamber view) of Patient 1, consistent with acute myocarditis (Lake Louise Criteria fulfilled). (A) Short tau inversion recovery image shows several areas of hyperintensity on the lateral wall of left ventricle (white arrows), indicating myocardial oedema. (B) T1 mapping image depicts multiple regions of increased myocardial T1 relaxation times (black arrows), reflecting myocardial injury. (C) Late gadolinium enhancement sequence shows extensive non-ischaemic late gadolinium enhancement on the same locations (arrowheads), indicating myocardial fibrosis.

case_images: On the sixth day of admission, cardiac magnetic resonance imaging (CMRI) revealed T1 and T2 criteria supporting the diagnosis of acute myocarditis, with inferolateral and apical predominance and no functional repercussions (Figure 1).

case_images: Cardiac magnetic resonance imaging images illustrating acute myocarditis in Patient 2. (A) Short tau inversion recovery image in a four-chamber view shows focal areas of hyperintensity on the septal and lateral walls of the left ventricle (white arrows), consistent with myocardial oedema. (B) T1 mapping image in a short-axis view highlights elevated T1 relaxation times (black arrows) in the myocardial tissue, indicating widespread myocardial injury. (C) Late gadolinium enhancement sequence in a four-chamber view reveals non-ischaemic late gadolinium enhancement at the septal and lateral segments (arrowheads), suggestive of myocardial fibrosis.

case_images: Five days after discharge, the patient had a CMRI (Figure 2) that showed signs of acute myopericarditis, with no impairment in heart function.
