Fatal underhanded chronic enterovirus infection associated with anti-CD20 monotherapy for central nervous system demyelinating disease.

We report a fatal case of coxsackievirus B4 chronic infection in a 30-year-old woman with a diagnosis of myelin oligodendrocyte glycoprotein antibody-associated disorder controlled by rituximab monotherapy for 3 years. Initially presenting as self-limited meningitis, the infection remained silent for 8 months before the sudden onset of fulminant myocarditis. Analysis of the complete genome showed that the same virus was responsible for both episodes.
