Abstract

Pseudochoreoathetosis can be found in association with lesions in the parietal lobe, thalamus (ventrolateral nucleus), brainstem or spinal cord due to severe proprioceptive deficits. We report right pseudochoreoathetosis in a 72-year-old woman with hypesthetic (> 50%) ataxic hemiparesis due to contralateral thalamogeniculate artery territory infarction involving the ventrolateral nucleus lesion. In our patient, proprioceptive deafferentiation may have played a key role in inducing pseudochoreoathetotic movements.KeyWords:Ventrolateral nucleus, Proprioception, Pseudochoreoathetosis
