[Abstract] Objective: To explore the clinical manifestations and imageology characteristics of hemichorea associated with non-ketotic hyperglycemia (HC-NH).Materials and Methods: The clinical and imaging data of 8 cases (male︰female=3︰5, age between 51 and 80 years) of HC-NH were analyzed retrospectively.Results: All the 8 cases were elderly T2DM patients, acute onset, characterized by unilateral involuntary choreiform movements, hyperglycemia, urine ketone negative, all involved the basal ganglia, 6 cases were left and 2 cases were right, the left head of caudate nucleus and the lentiform nucleus were involved in 3 cases, the left putamen was involved in 2 cases, the left head of caudate nucleus and the putamen were involved in 1 case, the right head of caudate nucleus were involved in 1 case, the right head of caudate nucleus and the putamen were involved in 1 case. T1-weighted imaging showed hyperintensity in all 8 cases, T2-weighted imaging showed isointensity in 4 cases, slightly lower hypointense in 3 cases and slightly hyperintensity in 1 case. T2-FLAIR sequence showed inhomogeneous hype-isointense in all 8 cases, DWI sequence showed isointensity in 5 cases, slightly lower hypointense in 3 cases, 2 cases in CT scan showed high density.Conclusions: The clinical manifestations of HC-NH are non-ketotic hyperglycemia, unilateral involuntary choreiform movements, and MRI is characterized.
