Abstract:
Chorea that occurs as a result of a stroke is rare. We report a patient who developed hemiplegia following an acute hemorrhagic stroke in the left cerebral peduncle and subthalamus; although he had recovered gradually from the severe limb weakness, monochorea occurred 6 months later. Pallidotomy eliminated this symptom and we found it is a safe treatment for medically intractable post-stroke chorea after hemiplegia has resolved.
