摘　　要：目的分析非酮症性高血糖所致脑部异常的CT和MRI表现,探讨其诊断意义。资料与方法回顾性分析6例临床以舞蹈症(n=3)、癫痫(n=3)为主要表现,且伴有脑部异常影像学改变的高血糖患者的CT及MRI资料。发病时患者血糖水平为21.9～43.2 mmol/L,平均32.4 mmol/L。尿酮体:(-)或(±)。结果头部CT示单侧或双侧基底节区高密度。MR T1WI多呈短T1信号,边界清楚;T2WI病灶呈低信号或混杂信号。结论非酮症性高血糖并发舞蹈症、癫痫可伴有脑部异常影像学改变,单侧或双侧基底节CT高密度及MRI短T1信号是其特点。Objective To analyze the CT and MRI features of brain caused by diabetes hyperglycemia, and to discuss the imaging diagnosis value. Materials and Methods CT and MRI abnormal brain findings of six patients caused by diabetes hyperglycemia were analyzed retrospectively, and associated with chorea or epilepsy as the cardinal clinical symptoms. Results All the 6 hyperglycemia patients were old persons combined with acute onset. 3 cases had the symptom of chorea, another 3 patients showed epilepsy. The blood glucose level was 21.9 -43.2 mmol/L, average 32.4 mmol/L. U- rine acetone bodies： （ - ）or（ ± ）. The brain computed tomographic scans showed slightly high density at the unilateral and/ or bilateral lenticular nucleus and caudate nucleus regions. The magnetic resonance imaging showed short T1 signal intensity on T1-weighted images, the boundary is clear. Low signal, high signal or mixed signal intensity were demonstrated on T2- weighted images. Conclusion The diabetes nonketotic hyperglycemia may accompany pars encephalic abnormal changes, the unilateral and/or bilateral basal ganglion high density image in CT and short-T1 signal in MRI were features of the primary disease.
