Acute hemichorea associated with ipsilateral chronic subdural hematoma

Here we are describing left-sided hemichorea in a 71-year-old female which developed within 3 days without any history of weakness, unconsciousness, fever, headache, vomiting. She had a history of head trauma 5 year back. No abnormality was detected in routine blood investigations. Computed tomography revealed a left chronic subdural hematoma. Neurosurgical intervention in form of left temporal “burr hole” drainage was performed and the patient’s involuntary movements improved in the postoperative period.
