【影像表现】：在磁共振T2加权和FLAIR像上可见尾状核与壳核双侧对称性均匀高信号影，T1低信号，弥散中等受限；内侧额叶和枕叶皮质在FLAIR像上表现为稍高信号；病变未累及丘脑和苍白球；脑沟和基底池明显增宽提示脑萎缩；脑桥和脑干未见异常信号影。jFr影像园XCTMR.com
There was bilateral and symmetrical uniformly high signal intensity in caudate nuclei, putamina on T2 weighted and FLAIR images. These was low signal on T1 weighted images. Moderate restriction was seen on diffusion weighted images.Medial frontal cortex and occipital cortex showed subtle hyperintensity on FLAIR.Thalami and globus pallidus were spared.Prominent sulci and gyri basal cisterns were present indicating cerebral atrophy.No abnormal signal intensities were seen in pons and brain stem.
