为探讨婴儿脚气病脑的CT特征和提高临床诊断水平,作者回顾分析了7例婴儿脑型脚气病的临床和CT资料。临床上主要以抽搐、精神萎靡、目光呆滞和呕吐等症状发病。脑CT显示:双侧豆状棱(5/7)、尾状棱头部(4/7)、丘脑(2/7)及齿状核(1/7)对称性低密度区和与年龄不相符的脑萎缩。维生素B_1治疗后,临床症状体征明显改善,于入院后2～5天痊愈出院。我们认为双侧豆状核、尾状核头部、丘脑及齿状校对称性低密度病变是婴儿脚气病性脑病的一种重要的CT征象。
In order to explore the CT features of infantile beriberi brain and to improve the clinical diagnosis, the authors retrospectively analyzed the clinical and CT data of 7 infants with brain beriberi. The main clinical twitch, apathetic, dull eyes and vomiting and other symptoms. Brain computed tomography (CT) showed symmetry low-density areas of bilateral bean-shaped ribs (5/7), caudate-shaped ribs (4/7), thalamus (2/7) and dentate nucleus Corresponding brain atrophy. Vitamin B_1 treatment, clinical symptoms and signs improved significantly, 2 to 5 days after admission cured. We believe that bilateral lentiform nuclei, caudate nucleus, thalamus and dentate symmetry of low density lesions is an important CT sign of infantile beriberi encephalopathy.
