Hemichorea associated with ketotic hyperglycemia: two cases report and literature review / 中华神经科杂志

Hemichorea associated with ketotic hyperglycemia is a lateral chorea caused by hyperglycemic ketosis, which is very rare clinically, and has not been reported at home and abroad in elderly patients with type 2 diabetes. Two cases with hemichorea associated with ketotic hyperglycemia were reported. One case was an 86-year-old female with primarily diagnosed diabetes and unilateral limb involvement. The other case was an 85-year-old man with chronic poor glycemic control and bilateral limb involvement. In order to improve the understanding of this disease, the clinical and imaging manifestations of this disease were analyzed in combination with relevant literature.
