目的 分析非乙醇中毒性韦尼克脑病(WE)患者的临床和颅脑MRI成像特点,探讨颅脑MRI对其的诊断价值. 方法 深圳市第二人民医院放射科自2007年6月至2010年2月应用MRI检查非乙醇中毒性WE患者5例,回顾性分析患者的临床特征、颅脑MRI成像特点及治疗转归等资料. 结果 非乙醇中毒性WE患者缺乏特征性临床表现,颅脑MRI主要表现为丘脑内侧,侧脑室,第三脑室,中脑导水管周围脑组织对称性高信号,2例患者可见大脑皮层受累.增强扫描后部分病变可见强化.2例患者死亡,3例患者应用维生素B1治疗后预后良好. 结论 颅脑MRI对非乙醇中毒性WE具有诊断价值,其显示的损害范围可反映WE的疾病严重程度.Abstract: Objective To analyze the clinical features and MR imaging features of patients with nonalcoholic Wemicke's encephalopathy (WE). Methods A retrospective review of the data,consisting of clinical and cranial MRI features, and the treatment results, was conducted on 5 patients with nonalcoholic WE, who admitted to our hospital fiom June 2007 to February 2010. Results The clinical features of nonalcoholic WE were non-characterized and most of them had no specific value for diagnosis. MR imaging showed symmetrical high signal in the medial thalamus, lateral ventricle, third ventricle and surrounding area of the aqueduct of midbrain; involvement of the cerebral cortex was found in 2 patients. Enhancement in some of the lesions was noted after performing contrast-enhanced scan.Favorable prognosis was given to the 3 patients treated with vitamin B1; 2 patients died. Conclusion Cerebral MRI enjoys great value in diagnosing nonalcoholic WE and reflects appropriately the pathological severity of this disease by demonstrating the scope of the lesions. 相似文献

韦尼克脑病三例的磁共振表现 总被引:10,自引:1,他引:10
韦尼克脑病(Wernicke encephalopathy)是一种由于硫胺缺乏所致的严重的营养代谢性脑病,常发生于乙醇中毒患者。磁共振成像(MRI)检查的普及对本病早期诊断很有帮助,国外已经有关于韦尼克脑病影像表现特点的报道[1-4]。我们确诊3例韦尼克脑病患者,对他们的影像学表现进行报道,并与既往我院报道的3例病理诊断的非乙醇中毒性韦尼克脑病的临床病理[5]加以对比,以提高临床医生对于该病影像学表现的认识。临床资料例1男性,46岁,因“头晕、呕吐、复视23d,意识模糊9d”于2004年2月10日入院。2001年7月患者因胃窦癌于我院行手术切除及术后化疗,术后… 相似文献

目的探讨韦尼克脑病(Wernicke’s encephalopathy,WE)的病因、发病机制、临床表现及治疗,提高对韦尼克脑病的认识和早期临床诊断率,减少临床误诊率。方法对济宁医学院附属医院肾内科、消化科、产科、神经内科、胃肠外科2005-01—2015-12收治的20例(男12例,女8例,年龄21~72岁)WE患者的病史、临床特征、诊断、治疗以及预后进行分析。结果饮酒为韦尼克脑病最常见的病因,临床表现多种多样,典型的临床表现为眼球运动麻痹、共济失调和意识精神障碍三大主征,但典型的WE"三联征"很少同时出现,20例患者中只有2例(10%)表现为典型的三联征。绝大多数患者经大剂量补充维生素B_1后疗效显著。结论 WE病因及临床表现复杂多样,早期诊断十分困难,颅脑MRI可作为诊断此病的重要辅助检查。及时大量补充维生素B_1可以明显改善患者预后情况。 相似文献

We assessed the prevalence of Wernicke encephalopathy (WE) in all 657 cases suspected of Creutzfeldt-Jakob (CJD) referred
from 2001 to 2006 to the French Neuropathology Network of CJD. Clinical, biological and imaging data were reviewed when the
diagnosis of WE was made at autopsy. No CJD was found in five cases suspected of sporadic CJD. In these five cases, myoclonus
had been observed in four, CSF 14-3-3 protein in two. In 14 other cases, WE was combined with CJD, 13 of which were sporadic.
These belonged mainly to the molecular variants of sporadic CJD associated with a long duration of disease. This stresses
the necessity of remaining alert to the diagnosis of WE when CJD is suspected. 相似文献

A report is presented on a patient with Wernicke's encephalopathy secondary to hyperemesis gravidarum. The 25-year-old female presented 11 weeks into pregnancy with prolonged vomiting. Neurological examination 8 weeks later demonstrated obtunded sensations, nystagmus and ataxia of gait. MR imaging revealed bilateral lesions in the mediodorsal nuclei of thalami, in the hypothalamus and in the periaqueductal gray matter (1). The neurological signs and the MRI findings pointed to a diagnosis of Wernicke's encephalopathy. The patient was treated with intramuscular vitamin B1 followed by oral thiamine until the end of pregnancy. The subsequent course of the pregnancy was uncomplicated, and resulted in the delivery of a healthy 2970 g male infant. A review of the literature published during the last 30 years revealed an additional 20 cases of Wernicke's encephalopathy induced by hyperemesis gravidarum. Only half of these pregnancies resulted in the birth of a normal infant. 相似文献

The nature and distribution of vascular changes in acute Wernicke's encephalopathy (WE) were analyzed in three autopsy cases. Lesions of the lateral vestibular nucleus of the medulla oblongata (three cases) and lateral ventricular wall (one case) were examined by reconstruction of 200 serial sections, and the capillary diameter in the tegmentum of the medulla oblongata was measured morphometrically in all cases. The vascular changes commonly found in and around the parenchymal lesions in all cases were: (1) dilatation and endothelial swelling of almost all vessels ranging from small arteries to veins, being especially severe with undulation in small arteries and arterioles, and (2) fibrinoid degeneration and hemorrhage involving selectively the arterioles and capillaries on the arterial side. These vascular changes in the medulla oblongata were essentially the same as those in the third ventricular wall, but differed in their severity. Capillary diameter in these cases was significantly larger than that in seven control cases. Such vascular changes, especially a dysoric change on the arterial side, could not be ascribed to secondary change following changes in the parenchyma, and were, therefore, considered to be a lesion essential to WE, as in the case of the parenchymal lesion. 相似文献

BackgroundAnti-Ma encephalitis is a disease usually associated with testicular cancer in young male patients. Anti-Ma encephalitis presented as Wernicke encephalopathy-like symptoms and with gastric cancer is rare. Here, we report a case of anti-Ma encephalitis with gastric cancer in an elderly patient, which has been misdiagnosed of Wernicke encephalopathy.Case reportA 71-year old male with a history of alcohol abuse was admitted to the hospital because of progressive dizziness, diplopia and anorexia lasted for 1 month. He was initially diagnosed as Wernicke encephalopathy. However, this patient failed in the treatment of VitB1. The blood and cerebrospinal fluid examination found the presence of anti-Ma1/2 antibodies. 18F-FDG PET-MR showed symmetrical hypermetabolic changes on the bilateral hypothalamus, basal ganglion and brainstem, as well as gastric neoplasms with liver metastasis. The patient was finally diagnosed with anti-Ma encephalitis.ConclusionAnti-Ma encephalitis should be suspected in patient with Wernicke encephalopathy-like symptoms but failed VitB1 treatment. 相似文献
