Human Parechovirus encephalitis is an uncommon infection. Very few of the cases have been reported in the literature so far. These reports are mainly about neonatal encephalitis, primarily affecting preterm neonates. Parechovirus encephalitis in otherwise healthy pediatric populations is a rare entity. Here, we present two unique pediatric cases secondary to Parechovirus infection, one with hemidystonia and another with acute onset of altered mental status, confusion, and headache.
Keywords: acute encephalitis; altered mental status; dystonia; encephalitis; movement disorder; parechovirus infection; pediatric hospital medicine; pediatric infectious disease; post-infectious; viral illness.
