Abstract

Japanese encephalitis is the one of the leading causes of viral encephalitis in Asia. We report on a 56-year-old man with Japanese encephalitis with an unusual manifestation of flaccid quadriplegia. Brain MRI revealed bilateral lesions in the thalamus, midbrain, and medial temporal lobe. Cervical MRI revealed lesion in the bilateral anterior spinal cord. Electromyography revealed active denervation in all four limbs and paraspinal muscles, suggesting a diffuse anterior-horn cell lesion. We report a patient with Japanese encephalitis accompanied by flaccid quadriplegia. Key Words: Japanese encephalitis, Flaccid quadriplegia
