ABSTRACT
CASE PRESENTATION This patient was first seen at age 38 years for evaluation of ballistic movements of the right upper extremity. At age 10 he had suffered a closed-head injury resulting in severe tremor of the right upper extremity. Five years later, he underwent ligation of the left anterior choroidal artery, a then controversial procedure to treat movement disorders. Postoperatively he had a right hemiparesis that slowly evolved into continuous jerking movements of the right upper extremity. In the years following the surgery, the patient suffered two subdural hematomas, resulting in a temporal contusion and a partial temporal lobectomy. Because of falling, he is wheelchair dependent.
