Abstract
|
|
|
|
Hemiballism is a rare hyperkinetic involuntary movement disorder that presents with unilateral forceful, flinging, large amplitude of proximal limbs. The most consistent neuropathological findings in hemiballism are a lesion of the contralateral subthalamic nucleus and pallidosubthalamic tract. However, we experienced a patient with pure hemiballism as isolated manifestation of acute ischemic stroke without other neurological abnormal symptoms such as chorea or dystonia. Brain magnetic resonance image showed acute ischemic stroke in right caudate nucleus but not subthalamic nucleus.
