Abstract

Posthemiplegic focal limb or hemidystonias are rare movement disorders usually due to vascular lesions of the contralateral basal ganglia. The pathogenesis of posthemiplegic dystonia is unknown and its management is usually difficult. In this paper, we report two patients who suffered from a single limb dystonia and hemidystonia, respectively. In the latter patient, hemidystonia developed due to an ischaemic cerebrovascular accident 2 or 3 months after the recovery of hemiplegia. Computed tomography and magnetic resonance imaging scans showed evidence of contralateral putamen and thalamus infarcts.
