摘要
目的 分析Marchiafava-Bignami疾病(MBD)的磁共振成像(MRI)表现特点,以提高MBD的MRI诊断水平.方法 回顾确诊的35例MBD患者的MRI资料,分析病灶分布及MRI信号特点.结果 35例患者中,胼胝体病变呈对称性分布,上下缘清楚,可见“夹心饼干”及中层坏死囊变征象.胼胝体以外病变最多分布于双侧半卵圆中心与额顶叶白质;其次分布于前连合与桥小脑中脚,极少数分布于颞枕叶白质、基底节区及皮质.结论 MBD的MRI影像具有特征性表现,可以作为诊断和鉴别诊断的重要方法.
Abstract
Objective To analyze the magnetic resonance imaging (MRI)features of Marchiafava-Bignami disease (MBD),in order to further improve the diagnosis level for MBD.Methods The MRI data of 35 cases who diagnosed as MBD was reviewed,and the MRI signal characteristics of lesions were analyzed.Results In the 35 patients,the corpus callosum lesions were symmetrical,the upper and lower edges were clearly visible with " sandwich biscuit" and middle cystic necrosis signs.The lesions outside the corpus callosum was mainly located in the center of bilateral half-oval and frontal and parietal lobes white matter; secondly distributed in anterior commissure and bridge cerebellar peduncle,and leastly located in the temporal occipital white matter,basal ganglia and cortex.Conclusion The MRI of MBD has characteristic manifest,and it can be used as an important method of diagnosis and differential diagnosis.
