Déjerine-Roussy syndrome presenting with atypical involuntary movements.

BACKGROUND

The Déjerine-Roussy syndrome is caused by a stroke in the posterior lateral nuclei of the thalamus. It has a 17 to 18% prevalence after a stroke involving the inferior lateral thalamus.

METHODS

We reported a case of a 65-year-old, diabetic and hypertensive male who presented with sudden onset of superficial hemianesthesia, allodynia, severe and paroxysmal pain on the right side of the body with choreoathetoid movements in the upperN limb, along with slured speech, and unsteadiness while walking.

CONCLUSIONS

It is characterized by superficial hemianesthesia, allodynia, severe paroxysmal pain, and choreoathetoid movements in the limbs on the paralyzed side. A posterior lateral thalamic lesion can present with ataxia hemiparesis contralateral to the side of the lesion.
