Bilateral Striatal Lesion Associated with Varicella

Abstract

Bilateral striatal lesion is characterised by a specific clinical syndrome (encephalopathy with rigidity, irritability, variable pyramidal, and extrapyramidal symptoms, speech abnormalities) and symmetrical lesion of the basal ganglia including the caudate nucleus, the putamen, and occasionally other nuclei. We report three cases in whom bilateral striatal lesion developed in association with varicella. Each patient recovered completely and showed no signs of cognitive deficiency, chorea or hyperkinetic syndrome, all of which have been reported as sequelae of BSL associated with other conditions. These cases suggest that bilateral striatal lesion may be an immune-mediated complication of varicella.

Key words

Bilateral striatal lesion - varicella - basal ganglia - caudate nucleus
