- Abstract
- Hemichorea is usually caused by lesions in the contralateral subthalamus and basal ganglia. Ipsilateral lesions have
rarely been reported to be responsible for the abnormal movement. A 27 year-old woman with well-controlled hyper-thyroidism
presented with sudden involuntary movements in the right limbs and a mild headache. The movements were
random, irregular, repetitive, and most prominent in the right hand and forearm, but also found in the right leg and face.
She experienced no weaknesses in the contralateral limbs. A brain magnetic resonance imaging(MRI) taken after 7
days showed early subacute hematoma in the right basal ganglia. There were no lesions in the left hemisphere. In a
cerebral angiography, the bilateral major cerebral vessels were narrowed around the circle of Willis. We critically
review previous reports of and explanations for the development of ipsilateral hemichorea.
