We report the reversible magnetic resonance imaging (MRI) findings in a 2-year-old girl with acute cerebellitis. The high signal intensity in the cerebellum was obvious on diffusion-weighted images, and the splenium of the corpus callosum also showed high signal intensity on T2-weighted images and on diffusion-weighted images. The lesion in the splenium quickly returned to normal 72 hours later, whereas the hyperintensity in the cerebellum persisted for 1 week until clinical improvement was achieved. The findings in our patient suggested the particular vulnerability of the splenium of the corpus callosum compared to other regions and the importance of the MRI examinations including diffusion-weighted images in the early stage of encephalitis.
我们报告了一名2岁急性小脑炎女童的可逆性磁共振成像（MRI）表现。小脑在扩散加权图像上高信号强度明显，胼胝体压部在T2加权图像和扩散加权图像上也显示高信号强度。胼胝体压部的病变在72小时后迅速恢复正常，而小脑的高信号持续1周，直至临床症状改善。我们患者的这些表现提示胼胝体压部相对于其他区域具有特殊易损性，以及包括扩散加权图像在内的MRI检查在脑炎早期的重要性。
