Severe Contralateral Striatal Hypometabolism in a Case of Diabetic Nonketotic Hyperglycemic Hemichorea on 18F-FDG PET/CT Brain

We present a case of elderly diabetic woman with poorly controlled blood glucose levels, presenting with choreiform movements limited to the right side. 18F-FDG PET/CT showed marked hypometabolism in the basal ganglia contralateral to the side with hemichorea. The metabolic dysfunctions lead to nonketotic hyperglycemic chorea, although poorly understood; the index case demonstrated severe glucose hypometabolism in the striatum and adds to the other reported differential diagnoses for striatal hypometabolism.
