1、堕堂堡堂垄查!生卷第3期JMedImagingVo1.25No.32015低血糖脑病MRI表现与临床分析相龙彬,宫元芳。,杨伟伟,侯兆惠,于龙,王光彬。(1.山东省威海市经济技术开发区医院1.放射科;2.医务科山东威海264205;3.山东省医学影像学研究所山东济南250021)【摘要】目的探讨低血糖脑病的MRI表现及临床鉴别。方法回顾分析我院2009年~2012年临床确诊的9例低血糖脑病的临床及MRI资料。结果本组最终确诊9例中5例有明确糖尿病病史,病程3~16年,1例脑挫裂伤术后半年,1例有节食瘦身行
2、为,1例长期大量饮酒,1例原因不明;突发偏瘫、失语5例,局灶性抽搐4例,躁动、情绪激越l例,表情淡漠、反应迟钝、视物模糊1例,昏迷1例;本组9例患者颅脑MRI检查均发现异常信号,8例表现为额、顶、枕叶皮层异常信号,1例胼胝体压部片状异常信号;TwI呈稍低信号,T。wI呈稍高信号,FLAIR序列呈高信号,DWI呈高信号,ADC图呈低信号;经治疗2周后4例复查MRI,病灶有明显吸收好转;8例患者经治疗后痊愈出院,1例死亡。结论临床上有脑卒中样表现的患者,需注意低血糖性脑病的可能,常规检测血糖及影像学检查对早期
3、正确干预具有重要意义;低血糖脑病发病部位及颅脑MRI信号表现具有一定特征性,DWI序列对病变更敏感,呈高信号。【关键词】低血糖脑病;磁共振成像;弥散加权成像中图分类号:R445.2;R742文献标识码:A文章编号:1006—9011(2015)03—0403—04MRIfindingsandclinicalanalysisofhypoglycemicencephal0pathyXIANGLong—bin,GONGYuan一ng,YANGWei—wei,HOUZao—hui,yULong,WANGGuang
