Hemiplegia: an initial manifestation of Japanese encephalitis.
A 7-year-old boy from an area endemic to Japanese encephalitis (JE) manifested with acute febrile illness, left hemiplegia and preserved consciousness during the prodromal phase of illness. The child developed features of encephalitis 48 hours after the onset of hemiplegia. IgM MAC ELISA for JE virus revealed high titers in the serum and cerebrospinal fluid suggestive of JE. MRI of the brain showed asymmetrical bilateral thalamic hyperintense lesions on T2 weighted image, considered diagnostic of JE. Hemiplegia during the prodromal phase or as an initial symptom of JE is rather unusual.
