Abstract
Non-ketotic hyperglycemia (NKHG) has been reported to increase the probability of seizures and movement disorders especially in elderly population. Here we report a case of long standing diabetes who presented with poor glycemic control and choreoathetoid movements of right upper limb, with Magnetic resonance imaging showing hyperintense lesion on T1 sequence in left basal ganglia suggestive of Diabetic striatopathy. These patients may get frequently misdiagnosed to have neurological disease, however recognition of this association is important as the condition may quickly resolve when NKHG is controlled.
Highlights
Hyperkinetic movement disorders are characterized by involuntary movements not associated with weakness
Chorea associated with non-ketotic hyperglycemia (NKHG) and high signal intensity lesions on T1-weighted brain magnetic resonance images (MRI) is recognized as a unique syndrome, known as diabetic striatopathy

Summary
Hyperkinetic movement disorders are characterized by involuntary movements not associated with weakness. Chorea associated with non-ketotic hyperglycemia (NKHG) and high signal intensity lesions on T1-weighted brain magnetic resonance images (MRI) is recognized as a unique syndrome, known as diabetic striatopathy. This has been mainly described to affect elderly women[3]. 55y/M, plumber by occupation, known case of T2 DM for 5 years, complicated by tripathy presented with history of sudden onset choreoathetoid movements right hand and right angle of mouth for 10 days. These involuntary movements were present even during sleep.
