Childhood chorea-encephalopathy associated with human parvovirus B19 infection.

An 8-year-old female presented with a distinct clinical course characterized by an acute self-limiting chorea-encephalopathy with cerebrospinal fluid (CSF)-specific oligoclonal bands. During the clinical course, genomic human parvovirus B19 DNA was detected in her serum and CSF. It was concluded that this patient represents the first published case of childhood chorea-encephalopathy associated with, and probably caused by, human parvovirus B19 infection.
