The T2-weighted imaging of the gadolinium-enhanced cardiac magnetic resonance imaging (A) showing a high signal gadolinium late enhancement and stain of the tissue in a part of the right ventricle and left ventricular posterior wall. Histopathological specimens from the inflammatory left ventricular myocardium with hematoxylin–eosin staining (B of 500 and D of 200 magnifications, respectively) showing the difference in the size of the myocardial cellular nuclei and eosinophilic changes in the cytoplasm and the invasion of the mononucleosis in the stroma (white arrows). Immunohistochemical staining (C of 500 and E of 200 magnifications, respectively) showing the monocytes indicating a positive leukocyte common antigen as a brown color (black arrows), positive CD3 of the T cellular marker, and negative CD20 of the B cellular marker. Bars in B, C, D, and E indicate 20 μm.
