title: Hemiballism in multiple sclerosis.
abstract: Hemiballism has rarely been reported in the setting of multiple sclerosis. Review of clinical descriptions cast some doubt on the accuracy of the diagnosis of the movement disorder in several previous cases. We report a patient with definite multiple sclerosis, with videotape documentation of hemiballism, and demonstration of a plaque in the contralateral subthalamic nucleus on a magnetic resonance image.
