Congenital lymphocytic choriomeningitis virus an underdiagnosed cause of neonatal hydrocephalus

We report a case of congenital hydrocephalus caused by lymphocytic choriomeningitis virus with severe neurologic sequelae, including hydrocephalus, chorioretinitis, blindness and developmental delay. This is the first report of lymphocytic choriomeningitis virus isolation in the cerebrospinal fluid of a congenitally infected infant.
