(A) A chest X-ray shows pleural effusion and enlarged heart shadow. (B,C) Diffuse patchy areas of edema (white arrow) and heterogeneous delay enhancement (black arrow) in the left ventricle on CMR images. (D) ECG demonstrates low voltage in all leads and ST-segment elevations of 2 mm in inferior wall leads and leads of V4, V5, and V6.

The 12-lead electrocardiography demonstrated low voltage in all leads and ST-segment elevation of 2 mm in inferior wall leads and leads of V4, V5, and V6 (Figure 1). Cardiac magnetic resonance (CMR) showed global gadolinium late enhancement and diffuse patchy areas of edema in the interventricular septum and lateral wall of the left ventricle (Figure 1).
Immunochemistry of lymph nodes derived from the neck area. (A) Atypical cells are positive for CD56. (B) Cells are also positive for EBV with in situ hybridization.

A immunohistochemical study showed that these malignant cells were positive for CD4, CD3epsilon, CD163, and CD56 (Figure 2). EBV in situ hybridization was also positive (Figure 2).
