Abstract
Movement disorders have been associated with hyperglycaemia including chorea, hemiballismus and choreoathetosis. In almost all documented cases, there is an association between clinical and radiological findings. We report a case of an 82-year-old man with hemichorea in the setting of hyperglycaemia and poorly controlled type 2 diabetes. He had subtle striatal changes on his radiology, and with intravenous fluids and insulin, his involuntary movements resolved on day 4, which correlated with improvement in glycaemic control. He was followed up through our local insulin stabilization programme after discharge.
