| 摘 要： | 目的探讨低血糖脑病的病因、临床和神经影像学特点。方法回顾性分析28例低血糖脑病患者的病因、临床和神经影像学资料。结果本组患者13例有明确糖尿病史,均行降糖药物治疗;8例患者疑糖尿病而服降糖药物,胰岛素瘤4例,原因不明3例。临床表现为意识障碍14例,言语不清、反应迟钝5例,偏瘫和单侧肢体瘫痪3例,精神行为异常3例,痫性发作3例。8例头颅CT或MRI未见明显异常;7例头颅CT示双侧基底节区对称性低密度灶,20例MRI检查异常,主要累及双侧基底节区、大脑皮质、皮质下白质、海马、胼胝体压部和脑干,表现为等或稍长T1、长T2异常信号,Flair像呈高信号,弥散加权成像(DWI)呈高信号。结论低血糖脑病的病因主要是过量使用降糖药物和胰岛素瘤,其临床表现复杂多样,动态监测血糖意义重大,MRI有高度特异性,DWI序列对病变更敏感。
