An 81-year-old woman with poorly controlled diabetes mellitus was hospitalized due to hemichoreahemiballism. A radiological examination revealed typical putaminal changes of diabetic hemichoreahemiballism (DHC-HB). Interestingly, brain computed tomography, performed before symptom onset, disclosed a hyperdense lesion in the left basal ganglia, indicating persistent basal ganglia impairment, even before the onset of symptoms, under sustained hyperglycemia. Additionally, an increase in the
