Zusammenfassung: | Complex hyperkinetic movement disorders are a rare complication of stroke, frequently involving posterolateral contralateral thalamic lesions. One of the proposed mechanisms for these presentations is proprioceptive impairment, hence not involving deregulation of the basal ganglia-thalamocortical circuits. We report a patient who presented with dystonic posturing and athetoid movements with onset 2 years after right frontoparietotemporal stroke. Brain MRI showed no thalamic lesion. Based on the phenomenology, a diagnosis of pseudochoreoathetosis was proposed. To our knowledge, this is the first case report of poststroke pseudochoreoathetosis without thalamic involvement. |
