摘　　要：目的总结Balo病同心圆性硬化的MRI表现及其诊断价值。方法搜集4例Balo病患者MRI资料,复习近年国内文献报道的13例Balo病同心圆性硬化的MRI表现。结果17例中表现为脑实质多发病灶16例,单发病灶1例;病变主要累及双侧或单侧大脑白质,其中并发脑干病变4例、小脑病变2例。典型同心圆性病灶在T1加权像上呈等、低信号交替环,T2加权像上呈等、高信号交替环;增强扫描等信号环强化。7例患者同时伴有典型多发性硬化斑块。结论Balo病同心圆性硬化的MRI表现具有特征性,是目前诊断Balo病最可靠的影像学检查法。Objective To summary MRI findings and its diagnostic value of Balo＇s concentric sclerosis . Methods Brain MRI images of 4 cases with Balo＇ s concentric sclerosis were studied with review of the literature in 13 cases. Results MRI showed multiple ring - like lesions within brains in 16 patients and single lesion only in 1, The deep white matters of cerebrum were involved in all patients. The cerebellum and brain stem were invaded in 2 and 4 respectively. Typical concentric sclerosis lesions demonstrated alternate middle and low signal rings on T1WI, middle and high on T2WI. The ring- like lesions were best seen on T1WI. The middle signal rings were enhanced on post -contrast images, The typical multiple sclerosis lesions were seen in 7 patients. Conclusion Balo＇ s concentric sclerosis has characteristic findings on MRI. MRI is a very reliable diagnostic methed for this disease,
