ObjectiveTo summarize the clinical characteristics and imaging manifestations of patients with nonketotic hyperglycemic hemichorea (NH‐HC) and to explore the possible pathogenesis, diagnosis. and treatment of the disease in order to improve the understanding of this disease and avoid misdiagnosis.MethodsRetrospective analysis was performed on the case data of five patients with NH‐HC admitted to our hospital in recent years. The patients were treated in the department of endocrinology, department of neurology, and department of neurosurgery in our hospital, respectively. Meanwhile, relevant literatures were consulted for further learning.ResultsNH‐HC is usually presented as a triad of nonketotic hyperglycemia, lateral chorea, and typical imaging manifestations of head magnetic resonance imaging or computed tomography, but the clinical manifestations are not the same, and imaging features may also be different, presenting a diversified trend in clinical practice. All five patients were given glucose‐lowering drugs and improved with or without combination of drugs to control symptoms of chorea.ConclusionNH‐HC is a rare complication of diabetes, characterized by hyperglycemia and hemichorea. How to identify the extreme situation and make fast judgment is a top priority. Timely and correct control of blood glucose is the key to the treatment, and when necessary, application of dopamine receptor antagonists in patients with combination therapy can accelerate improvement of the clinical symptoms. The prognosis of NH‐HC is good, the clinician should strengthen comprehensive understanding of this disease to avoid missed diagnosis or misdiagnosis and enable patients to get more timely and effective treatment.image

非酮症高血糖性偏侧舞蹈症临床特点及影像学表现的进一步认识

目的总结非酮症高血糖偏侧舞蹈症（NH-HC）患者的临床特点和影像学表现，探讨可能的发病机制和诊断。方法对我院近年来收治的5例NH-HC患者的病例资料进行回顾性分析。患者分别在我院内分泌科、神经内科、神经外科接受治疗。同时查阅相关文献进一步学习。结果NH-HC通常表现为非酮症高血糖、侧向舞蹈症以及头颅磁共振或CT的典型影像学表现三联征，但临床表现不尽相同，影像学表现也不尽相同。特点也可能不同，临床实践呈现多元化趋势。所有 5 名患者均接受降糖药物治疗，联合或不联合药物控制舞蹈病症状均得到改善。结论 NH-HC 是一种罕见的糖尿病并发症，以高血糖和偏侧舞蹈症为特征。如何识别极端情况并快速做出判断是当务之急。及时正确控制血糖是治疗的关键，必要时患者应用多巴胺受体拮抗剂联合治疗可加速临床症状的改善。 NH-HC预后良好，临床医生应加强对该病的全面认识，避免漏诊或误诊，使患者得到更及时、有效的治疗。图像
