ECG monitoring revealed an intermittent atrioventricular block type Mobitz 2 (Fig. 1). T2-weighted and late gadolinium enhancement images (Fig. 2 and Additional file 1). Therefore, to rule out a peri-myocarditis, serologic studies, including parvovirus-B19, streptococcus, influenza-virus, mycoplasma, adenovirus, enterovirus, herpes virus type 6 and cytomegalovirus were performed, which did not support the diagnosis.

T2-weighted and late gadolinium enhancement images (Fig. 2 and Additional file 1). Therefore, to rule out a peri-myocarditis, serologic studies, including parvovirus-B19, streptococcus, influenza-virus, mycoplasma, adenovirus, enterovirus, herpes virus type 6 and cytomegalovirus were performed, which did not support the diagnosis. In a follow-up MRI investigation after 3 weeks, the initially increased signal intensity in the epicardial layer in T2-weighted and late gadolinium enhancement images had been dissolved (Fig. 3 and Additional file 2).
