Summary
An unusual case of hemiballismus following closed head injury is presented. The abnormal movement persisted for 16 years despite medical treatment. Preoperative studies did not reveal a specific lesion within the subthalamic nucleus or within the basal ganglia. A stereotactic ventral intermediate thalamotomy was performed producing a complete resolution of the ballistic movement which persisted for the length of our 12-month follow-up.
