Nonketotic hyperglycemic hemichorea (NH-HC) is a rare condition presenting in the clinical setting. Brain imaging plays an important role in diagnosing NH-HC, which typically shows basal ganglia changes contralateral to the side of the hemiballismus/hemichorea. Only a few articles in the literature have reported normal pertinent magnetic resonance/CT findings in patients presenting with NH-HC. To the authors' knowledge, no cases in the literature have reported basal ganglia changes solely observed on CT but not on MRI in patients presenting with NH-HC. Herein, we describe a unique case in which a CT of a patient presenting with NH-HC demonstrated basal ganglia abnormalities with negative MRI findings.
非酮症高血糖性偏侧舞蹈症（NH-HC）是一种临床少见病症。脑部影像学检查在NH-HC的诊断中起着重要作用，其典型表现为与偏侧投掷症/偏侧舞蹈症同侧的基底节区改变。文献中仅有少数文章报道了NH-HC患者的相关磁共振成像/计算机断层扫描（MRI/CT）结果正常。据作者所知，文献中尚无NH-HC患者仅在CT上而非MRI上观察到基底节区改变的病例报道。在此，我们描述了一例独特病例，该NH-HC患者的CT显示基底节区异常，而MRI结果为阴性。
