Cytomegalovirus (CMV) and Acute Myocarditis in an Immunocompetent Patient

抄録

Acute viral infections can lead to heart inflammation, including acute myocarditis. We report a rare case of myopericarditis in a young immunocompetent adult, in a context of recent Cytomegalovirus (CMV) infection.
The clinical presentation was an influenzae-like syndrome, classical for a CMV infection, without any chest pain or dyspnea, but a systematic exploration showed multiple inflammation-compatible myopericardial images on MNR-scan. The diagnosis of asymptomatic myopericarditis was established. We present the MNR-scan findings and discuss the CMV cardiac effects and systematic cardiac MRI interest in viral infection.
