Japanese encephalitis in Western Europe.

Japanese encephalitis is the leading cause of viral encephalitis in Asia. In Western Europe, however, Japanese encephalitis has not been reported so far. We report on a 59-year-old German woman with typical neurological symptoms and clinical presentation 8 days after a journey to northern China. The case report summarizes the patient's clinical course as well as pathological findings in blood samples, the cerebro-spinal fluid, MRI scans, and EEGs.
