小儿维生素B1缺乏性脑病的CT诊断价值

目的 :探讨维生素B1 缺乏性脑病的CT表现特征和诊断价值。方法 :对临床确诊的 12例维生素B1 缺乏性脑病患儿行颅脑常规CT扫描 ,并对其颅脑CT表现及临床资料进行综合分析。结果 :其中对称性的低密度见于尾状核和豆状核 7例 ,豆状核 3例 ,豆状核及颞叶 2例。经CT诊断的该组病例治疗取得明显的效果 ,5例治疗 1周后CT复查 ,2例基底节病灶消失 ,3例病灶明显减小。 2例患儿出现脑瘫后遗症 ,CT显示基底节区有对称性的囊变灶。结论 :小儿维生素B1 缺乏性脑病患儿 ,其颅脑CT表现两侧基底节区对称性的低密度改变有一定特征性 ,CT对该病诊断以及预后判断有重要价值。

The value of CT in diagnosis of cerebral vitamin B1 deficiency

Objective:To study the CT features of cerebral vitamin B 1 deficiency and its diagnostic value.Methods:12 cases of cerebral vitamin B 1 deficiency diagnosed by clinical features,were performed CT scanning. The CT findings and clinical data were comprehensively analyzed.Results:CT scans showed bilateral symmetric hypodense lesions in the basal ganglion.Following treatment,CT scans showed disappearance of hypodense lesions in 2 of 5 cases,diminution of area of hypodense lesions in 3 of 5 cases.Cerebral palsy was resulted in two cases,and CT showed bilateral symmetric cystic hypodense lesions in the basal ganglion.Conclusion:Bilateral symmetric hypodense lesions in the basal ganglion are important signs of cerebral vitamin B 1 deficiency on CT,and CT is valuable for the diagnosis of this disease.
