Hemichorea in a patient with ipsilateral cortical infarction: a case report.

ABSTRACT:

Background

Hemichorea is usually caused by contralateral deep structures of brain. It rarely results from acute cortical ischemic stroke and that caused by ipsilateral brain lesions is even rarer.

Case presentation

A 64-year-old female presented with acute obtuseness and left-sided hemichorea. She had a history of right frontal lobe surgery and radiotherapy due to brain metastasis from lung cancer 8 years ago.

The choreatic movement remitted after antipsychotic treatment.

Conclusion
