摘要
目的 :分析胼胝体梗死的MRI表现和特征。方法 :13例胼胝体梗死患者 ,9例有高血压病史 ,4例有糖尿病 ,而同时合并有高血压及糖尿病者 3例 ,13例均行MR检查。结果 :梗死发生于胼胝体膝部者 2例 ,体部 8例 ,其中 3例为胼胝体体部多发梗死 ,1例为膝部和体部多发病灶 ,3例发生于压部 ,大小为 0 .2cm× 0 .3cm~ 1.1cm× 4.0cm。不同程度的伴有底节区、丘脑、脑干等部位的梗死。MRI上 ,T1 加权像呈低信号 ,T2 加权像上表现为高信号 ,增强扫描病灶表现为不强化或轻度不均匀强化 ,Flair序列为高信号。结论 :MRI可有效、准确、全面地显示胼胝体梗死的大小、范围以及合并的其他部位的病灶。
Objective:To analyze the MRI features of the corpus callosum infarction.Methods:In 13 cases of corpus callosum infarction,9 patients had a long history of hypertension,4 had diabetes mellitus and 3 cases had a long history of both diseases. all patients were examined by MRI.Results:The infarctions were in the genu(n=2). in the body(n=8),and in the splenium(n=3) and three patients had more than one lesion in the body. One case had two infarctions in the genu and body separately. The size of the infarction was 0.2cm×0.3cm to 1.1cm×4.0cm.Conclusion:MRI can clearly and accurately show the size and location of the corpus callosum infarction.
