目的探讨糖尿病性偏侧舞蹈症的临床表现、发病机制及影像学表现。方法分析了2例糖尿病性偏侧舞蹈症患者的临床表现、治疗经过及影像改变,并学习相关文献。结果2例糖尿病患者均未经过糸统的降血糖治疗,且均为非酮症高血糖患者。2例患者均为急性起病,出现一侧肢体舞蹈样运动,睡眠时消失,早期CT表现为患肢对侧侧尾状核、壳核和(或)苍白球高密度影,一个月左右减弱或消失。MRI则表现为病灶区T1为高信号,T2为低信号或高信号,边界清晰,无水肿征象。结论糖尿病性偏侧舞蹈症多见于未糸统控制血糖的糖尿病患者,发病部位以纹状体为主,CT早期表现为高密度影,易与脑出血相混淆,MRIT1像为高信号,T2像为低信号或高信号认识该疾病可以使糖尿病患者得到及时有效的治疗,防止误诊误治的发生。 Objective To investigate the clinical manifestations, pathogenesis and imaging manifestations of diabetic hemophthalmos. Methods The clinical manifestations, treatment and imaging changes of 2 patients with diabetic hemophthalmos were analyzed and related literatures were studied. Results None of the two diabetic patients had undergone systemic hypoglycemic therapy and were non-ketotic hyperglycemic patients. 2 patients were acute onset, there is one side of the body dance-like movement, disappear during sleep, early CT showed limb contralateral caudate nucleus, putamen and (or) globus pallidus high density, a month or so weakened Or disappear. MRI showed lesions T1 high signal, T2 low signal or high signal, clear boundary, no edema signs. Conclusions Diabetic hemDhylaxis is more common in diabetic patients with uncontrolled blood glucose control. The main part of the disease is striatum. CT is characterized by high density in the early stage of CT, which is easily confused with cerebral hemorrhage. MRIT1 is a high signal and T2 Awareness of the disease for low or high signals can lead to timely and effective treatment of diabetic patients and prevent the occurrence of misdiagnosis and mistreatment.
