This multicenter retrospective study enrolled patients with acute-onset hemichorea/hemiballismus, nonketotic hyperglycemia (random blood glucose ≥11.1 mmol/L), and basal ganglia abnormalities on MRI. Clinical outcomes, metabolic profiles, and neuroimaging features (including T1-weighted hyperintensity, DCE-MRI, and MRS) were systematically analyzed.</p><p><strong>Results: </strong>The cohort exhibited a mean age of 68.6 ±10.4 years (range 48-89), with equal gender distribution. Hyperglycemia (mean HbA1c 11.4%±3.8%) and T1-weighted hyperintensity in the contralateral basal ganglia were universal (91.3% on MRI). Notably, 26.1% of patients presented with normoglycemia at admission yet exhibited typical chorea, challenging the \"hyperglycemia-first\" paradigm. Follow-up MRI revealed dynamic changes in T1 signal intensity, with 2 cases demonstrating symptom exacerbation despite signal resolution. NKHC manifests heterogeneous clinical and imaging phenotypes, suggesting a multifactorial pathogenesis involving metabolic derangement, cerebrovascular insufficiency, and blood-brain barrier disruption. Normoglycemic presentations and paradoxical imaging changes warrant further mechanistic exploration.</p><p><strong>Conclusions: </strong>To our knowledge, this study represents the largest case series of nonketotic hyperglycemic chorea to date, offering valuable insights into the clinical and imaging characteristics of this condition.</p>","PeriodicalId":520805,"journal":{"name":"The Journal of clinical endocrinology and metabolism","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
