AbstractDiabetic striatopathy is a rare and life-threatening manifestation of diabetes mellitus. The disease commonly affects individuals of Asian descent, females, and the elderly. Patients usually present with hemiballism-hemichorea caused by nonketotic hyperglycemia. Hemiballism-hemichorea is defined as involuntary continuous random appearing movement involving one side of the body. This movement disorder may develop secondary to stroke, diabetic striatopathy, neoplasm, infection, Wilson's disease, and thyrotoxicosis. Despite being rare, prompt recognition of a hyperglycemia-induced hemiballism-hemichorea is essential because the symptoms are reversible with correction of hyperglycemia. Diagnosis is possible based on blood analysis and neuroimaging findings. Laboratory tests reveal raised blood glucose and hemoglobin A1C levels which indicate poorly controlled diabetes. Neuroimaging provides suggestive findings of diabetic striatopathy which are hyperattenuation on computed tomography and hyperintensity on T1-weighted magnetic resonance imaging in the basal ganglia. In this case report, our aim is to present neuroimaging findings in an adult man with sudden onset of hemiballism associated with nonketotic hyperglycemia.
