Viral infection of central nervous system (CNS) is a common problem worldwide, especially in children. The clinical manifestations of viral CNS infection are the most important clues for diagnosis and treatment. The 1-year prospective study to explore the prevalence, clinical manifestations, and laboratory findings of viral CNS infection in children, including human herpes virus (HHV) type 1, 2, 3, 4, 5, 6A, 6B, 7, enterovirus B, mumps virus, measles virus, Japanese encephalitis virus, JC virus, BK polyomavirus, Nipha virus and influenza virus (H1N1, H3N2) were performed. Total of 71 children suspected CNS infection, aged between 2 days to 12.9 years were enrolled from May 2009 to April 2010. Total 4 children with non CNS infection, 5 bacterial meningitis, 2 tuberculous meningitis CNS infection were excluded. The HHV2 (50.0%) was the most common viral CNS infection. Other viral CNS infection included HHV1 (11.60%), VZV (6.7%), HHV6 (3.3%), HHV7 (3.3%), enterovirus B (1.67%) and H3N2 (1.67%). Diarrhea, irritability and CSF pleocytosis may helpful for differentiation between subtype of viral CNS infection.

We report the clinical and neuroimaging findings of an immunocompetent patient with concurrent pneumococcal and West Nile virus meningoencephalitis with relapsing clinical course despite a full course of antibiotic treatment. The patient developed acute oculomotor nerve palsy with pupillary involvement and bilateral hearing loss, and delayed right leg monoparesis. We speculate that coexisting bacterial and viral neuroinvasive infections contributed to the unusual clinical and imaging manifestations, and that overwhelming laboratory and clinical features of bacterial meningitis masked the typical features of CNS viral infection. Therefore, atypical presentations of bacterial meningitis should raise a high index of suspicion for coexisting infections, even in immunocompetent patients, and evolving neuroimaging findings may be helpful in substantiating clinical suspicion and guiding further management.
