Abstract

Post-encephalitic parkinsonism is a well-known entity, but involvement of the basal ganglia is rarely documented. We describe a 21-year-old man who developed parkinsonism following encephalitic illness presumed to be of viral origin with substantia nigra lesions evident on magnetic resonance imaging scan.
