Akinetic rigid syndrome as a presenting feature of subacute sclerosing pan encephalitis

Abstract

Atypical presentations of subacute sclerosing panencephalitis include hemiparesis, acute disseminated encephalomyelitis, cerebellar ataxia, visual disturbances, symptoms suggestive of the intracranial space-occupying lesion, and extrapyramidal movement disorders. Parkinsonism as the presenting feature of subacute sclerosing panencephalitis is a rare occurrence. Here we report a child who presented with bradykinesia and rigidity, underwent extensive investigations, finally turned out to be subacute sclerosis panencephalitis.
