Level I Hyperglycemia Alert: A Case Report

Abstract

Introduction: Nonketotic hyperglycemia-associated chorea is a rare condition that upon presentation to the emergency department can be easily misdiagnosed as a seizure or a stroke. Although uncommon, identification of this condition can aid emergency physicians in avoiding unnecessary and potentially harmful treatments for other neurological pathology. Furthermore, prompt hyperglycemic control can result in reversal of symptoms within days. Case Report: We present a case of nonketotic hyperglycemia-associated chorea where the patient was transferred to our facility as a hemorrhagic stroke alert, based on a false-positive interpretation of head computed tomography (CT) imaging. Conclusion: Nonketotic hyperglycemia on CT imaging and clinical presentation can mimic stroke presentations. Prompt recognition of key features can lead to appropriate treatment.
