Objective: To explore the clinical manifestations, diagnosis, treatment, and pathogenesis of diabetic striatopathy (DS) to improve the understanding of the disease and avoid misdiagnosis or underdiagnosis.
Methods: The clinical, laboratory, and imaging data of 6 patients (5 Asian females and 1 Asian male) with diabetic striatum were analyzed retrospectively, and the related literature was reviewed.
Results: All 6 patients showed hyperglycemia, 5 patients presented with involuntary movement of unilateral limbs, and 1 with unilateral limb numbness. Besides, 5 patients (except case 3) underwent MRI examinations that showed hyperintensity in unilateral caudate and lentiform nucleus on T1-weighted images. And all 6 patients who underwent brain CT examinations showed hyperdensity or isodensity in unilateral caudate and lentiform nucleus. None had a family history of similar abnormal movements. After blood glucose control and symptomatic support treatment, the symptoms of all patients improved to various degrees, and reexaminations showed that the lesions gradually disappeared.
Conclusion: Diabetic striatal disease is a rare complication of diabetes mellitus, the result of a combination of different pathogenesis. It is characterized by hyperglycemia, hemichorea, and contralateral striatal T1WI hyperintensity or CT hyperdensity. Both ketosis and nonketotic hyperglycemic hemichorea have typical imaging manifestations. The prognosis is excellent when this disease is detected early, and the lesions can be gradually absorbed and dissipated with glycemic control.

Diabetes mellitus is one of the most frequent endocrinopathies in the medical routine, appearing across different specialties. Although neurological involvement in the form of peripheral neuropathy is the most recurrent form acknowledged by physicians, the spectrum of neurological involvement can be more diverse. Here, we present a case of diabetic striatopathy, a rare neurological manifestation of diabetes mellitus with poor metabolic control, in a patient whose epidemiological group was not classically.

Background: Diabetic striatopathy (DS) is a rare disorder characterized by clinical manifestations of hemichorea, non-ketotic hyperglycemia, and high signal on T1-weighted MRI or high density on CT scan in basal ganglia, typically associated with poor glycemic control.
Objective: This study aimed to analyze clinical characteristics of patients with diabetic striatopathy to raise awareness amongst physicians, especially endocrinologists, about this rare neurological manifestation in patients with diabetes.
Methods: We retrospectively analyzed the data on clinical presentations, laboratory workups, and cranial CT and MRI of six patients with DS who were admitted to our hospital from October 2013 to June 2022.

Article Synopsis
- - Chorea, which is characterized by involuntary limb movements, is rare in patients on maintenance dialysis but significantly impacts their quality of life, with limited prior documentation on the condition.
- - Two hemodialysis patients with end-stage renal disease experienced worsening involuntary movements; one was treated for diabetic striatopathy, while the other for uremic metabolic encephalopathy, both with subsequent symptom improvement.
- - The cases highlight that choreiform movements in hemodialysis patients can arise from different causes, indicating a need for careful diagnosis and treatment in the early stages of dialysis.

Movement disorders associated with diabetes mellitus (DM) are rare. The diagnosis of diabetic striatopathy (DS) is based on the presence of a triad characterized by hyperglycemia, hemiballismus/chorea, and hypersignal of the basal ganglia on T1-weighted MRI. In most cases, treatment involves glycemic control.

Nonketotic hyperglycemia-induced hemichorea is a rare condition of type 2 diabetes. It is characterized by hyperglycemia with the symptom traced to the basal ganglion like hemichorea or hemiballism, with the hyperintensity within basal ganglion presented in computed tomography (CT) or hyper signal in T1-weighted magnetic resonance image (MRI). It was also confirmed with a relatively better prognosis in that the symptoms of these patients could be relieved after the alleviation of hyperglycemia.
