摘要
目的:分析非酮症高血糖伴偏身舞蹈症患者脑部的影像学表现。方法:回顾性分析9例非酮症高血糖伴偏身舞蹈症患者的脑部CT和MRI表现。9例患者均接受至少1次CT平扫,其中6例接受至少1次MRI平扫,2例行MRI增强检查,1例行MRA检查。7例治疗后接受复查。结果:9例CT均见基底节区片状稍高或高密度影,T1WI表现为基底节区片状稍高或高信号,边界较清晰,T2WI表现为等信号或稍低信号,DWI示病变区为稍低信号,病变均具有无占位效应、周围无水肿、边界清晰及无强化的特点。6例治疗后血糖降到正常范围,复查头部CT或MR,其中2例病变消失,2例病变缩小,3例未见改变。结论:非酮症高血糖伴舞蹈病具有特征性临床及影像学表现。
Objective:To analyze the brain imaging manifestation of patients with nonketodc hyperglycemia and partial chorea.Methods:The brain CT and MRI manifestations of 9 patients with nonketodc hyperglycemia and partial chorea were retrospectively analyzed.9 patients were accepted at least one time of CT scan.6 cases were accepted at least one time of MR scan.2 cases were accepted MRI enhancement examination.1 case was accepted MRA examination.7 patients were accepted a review after treatment.Results:9 cases of CT were seen the basal ganglia region slightly high or high density shadow,T1 WI performance was the basal ganglia region flake slightly higher or high signal,the boundary was clear,T2 WI performance was such as signal or slightly low signal,DWI showed that the lesion area was slightly low signal,the lesion had the characteristics of no placeholder effect,no edema around,clear boundaries and no enhancement.The blood glucoses were decreased to the normal range after treatment in 6 cases.The head CT or MR was reviewed,including 2 cases were disappeared,2 cases were reduced,3 cases had not been changed.Conclusion:Nonketodc hyperglycemia with partial chorea have characteristic clinical and imaging manifestation.
