摘要
目的分析线粒体脑肌病患者的MRI表现,以期提高对该病的认识。方法回顾性分析临床确诊的5例线粒体脑肌病患者的MRI表现。结果5例患者脑实质MR均呈长T1长T2信号,其中1例仅累及双侧苍白球,4例累及灰白质;3例并幕上脑室扩大,2例并小脑萎缩,1例并双侧基底节钙化。结论MRI可以清晰显示线粒体脑肌病的脑内病变。确诊需结合临床。
Objective To analyze MRI findings of the mitochondrial encephalopathy, in order to improve the understanding of this disease. Methods MR findings of 5 patients of clinically proved mitochondrial encephalopathy were retrospectively analyzed. Results Brain parenchymal lesions in all patients were low intensity on T1WI and high signal intensity on T2WI. One patient had bilateral globus pallidus involvement, while involvement of gray matter and white matter were observed in 4 patients. Three patients had enlargement of supratentorial ventricles, 2 patients had cerebellar atrophy and 1 patient had bilateral basal galia calcification. Conclusion MRI can show the intracranial lesions in patients with mitochondrial encephalomyopathy clearly, but accurate diagnosis should depend on clinical data.
