Non-ketotic hyperglycemic hemichorea-hemiballismus syndrome is a rare neurological condition associated with hyperglycemia from uncontrolled type 2 diabetes mellitus. The disease is diagnosed via clinical presentation, laboratory evaluation, and neuroimaging. With a prompt diagnosis, glycemic control is initiated as the mainstay of treatment. Additional management of chorea symptoms can be completed with neuroleptics. Here, we report a case of a 54-year-old male individual presenting with unilateral, involuntary, and uncontrollable muscle contractions secondary to non-ketotic hyperglycemia. He was managed with strict glycemic control only. Significant improvement in symptoms was noted two months after diagnosis. A complete recovery is expected within six months of onset.
