Bilateral intracerebral haemorrhages: an atypical presentation of Japanese encephalitis.

ABSTRACT

Japanese encephalitis is common human endemic encephalitis seen over various parts of the world. Usual presenting features include an encephalitic syndrome, symptoms of frontal lobe, basal ganglia and thalamic involvement. Characteristic radiological picture is bilateral thalamic and basal ganglia hypo density in the CT scan and hypo-intensity in T1 and hyperintensity in T2 weighted image in MRI. Very rarely occurrence of bilateral hemorrhage may be seen in these regions. This radiological change may be early indicator of the disease before serological confirmation by the available diagnostic modalities. In this communication, we have reported a case of Japanese encephalitis presented with bilateral basal ganglia hemorrhages.
