Chorea is a hyperkinetic movement disorder characterized by involuntary, short-lasting, random, and irregular contractions conveying a feeling of restlessness to the observer which may be caused by hereditary neurodegenerative diseases, damage to the deep brain structures, autoimmune disorders, metabolic derangements or certain drugs and hormones. Non-ketotic hyperglycemia is a well-described endocrine disturbance that can lead to hemichorea or generalized chorea where striatopathy is commonly found in imaging. Here we present a case of nonketotic hyperglycemic hemichorea with typical striatopathy on neuroimaging. The choriform movements gradually resolved over two weeks after achieving blood sugar control and treatment with neuroleptics.
