     [摘要] 目的 评价颅脑MRI检查在非酒精中毒性韦尼克脑病诊断中的价值。方法 对4例非酒精中毒性韦尼克脑病患者的临床特征、颅脑MRI影像及治疗转归等资料进行统计、对比、分析。结果 本组颅脑MRI显示,两侧丘脑内侧、第三脑室周围、导水管周围、前联合、视交叉、延髓背侧可见多发对称性长T1长T2信号影,T2FLAIR呈高信号影,两侧侧脑室旁T2FLAIR可见多发小片状高信号影,脑室系统未见异常,中线结果居中。随访显示4例康复患者,随着临床表现好转,其颅脑MRI异常信号逐渐消失。结论 颅脑MRI检查对非酒精中毒性韦尼克脑病具有重要诊断价值,其异常信号显示的范围反映了疾病的严重程度。

    [Abstract] Objective To evaluate the diagnostic value of cranial MRI for non-alcoholic Wernicke's encephalopathy. Methods Clinical features,cranial MRI images and treatment outcome and other data of four cases of non-alcoholic Wernicke's encephalopathy patients were compared and statistically analyzed. Results The cranial MRI showed that both sides of the medial hypothalamus,three ventricle around inside the thalamus,periaqueduct,the former joint, optic chiasm, dorsal medulla had multiple symmetric long T1,T2 signal intensity,T2FLAIR showed high signal intensity,and both sides lateral side T2FLAIR seen multiple small pieces of high signal intensity,ventricular system was normal,and the results of the center line was central. Follow-up showed four cases of patients of rehabilitation with clinical improvement,their cranial MRI signal abnormalities gradually disappeared. Conclusion Cranial MRI examination for non-alcoholic Wernicke's encephalopathy has important diagnostic value,and the range of the abnormal signal display reflects the severity of the disease.

    韦尼克脑病(Wernicke’s encephalopathy,WE)是由于各种原因造成的维生素B1缺乏导致的神经系统的代谢性疾病,主要为酒精中毒性的。维生素B1(硫胺素)缺乏的主要原因有进食不足、吸收不良、营养代谢障碍等。而非酒精中毒性的相对罕见,临床易忽视[1]。现将4年来我院收治的4例韦尼克患者的临床、MRI资料与随访结果报道如下。

    1 资料与方法

    1.1 一般资料

    本组男3例,女1例,年龄28~53岁,平均43岁。1例男患者为胃癌、胃大部切除术后;1例男患者有嗜酒20余年,1例男患者有经常性饮酒史10余年,另1例无饮酒史。有胃切除病史患者考虑维生素B1缺乏,拟诊韦尼克脑病;另3例患者均有急性胰腺炎的症状、体征及实验室指标,拟诊为急性胰腺炎。

    1.2 临床表现

    首发表现为头晕、嗜睡、表情淡漠、记忆障碍、共济失调;临床诊断为韦尼克脑病时浅昏迷。

    1.3 检查方法

    采用GE Signa HD 1.5T超导型MR成像设备,8通道头部线圈,行常规头颅横断位T1WI、T2WI、FLAIR和矢状位T2WI序列检查。扫描参数:SE T1WI:TR 380~500ms,TE 8~16ms;FSE T2WI:TR 4200~4500ms,TE 87.6~98.6ms;FLAIR:TR 9002ms,TE 133ms,TI 2200ms。视野20~24cm,层厚5mm,间隔1mm,矩阵256×256或224×256。

    1.4 治疗与预后

    本组患者均给予大量的维生素B1 ......
