We present findings on MR imaging in 5 patients with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). In the literature, early atrophy of the superior vermis as well as progressive atrophy of the cerebellar hemispheres and cervical cord was described. We found linear hypointensity on T2 and T2 fluid-attenuated inversion recovery-weighted images in the pons in all of our 5 patients.
我们展示了5例患有夏尔勒沃-萨格奈常染色体隐性痉挛性共济失调（ARSACS）患者的磁共振成像结果。在文献中，曾描述过小脑上蚓部早期萎缩以及小脑半球和颈髓的进行性萎缩。我们发现，在我们所有5例患者的脑桥中，T2加权像和T2液体衰减反转恢复加权像上均出现线状低信号。
