Co-infection of neurocysticercosis with Japanese encephalitis: coincidence or synchronism?

We report the case of an eight-year-old boy who presented with an acute encephalitis and was confirmed to have Japanese encephalitis (JE). In addition, we found the vesicular stage of neurocysticercosis (NCC). The co-occurrence of JE and NCC was thought to be synergistic as there is some evidence that in presence of NCC, the neuroinvasiveness and virulence of JE is greater and associated with poor outcome.
