A 66-year-old man was admitted to our department with anterograde amnesia. He was diagnosed with transient global amnesia (TGA) because of the symptom lasting for several hours and no abnormal findings on MRI and EEG. About a year after the episode, he recurred amnesia lasting only for 20 minutes. MRI diffusion weighted image (DWI) revealed a small hyperintense signal in the right hippocampus, while there was no abnormality on EEG. We diagnosed him with recurrent TGA. This case may be interesting in that symptom duration and MRI-DWI finding are much different between two attacks of TGA.
一名66岁男性因顺行性遗忘入住我科。由于症状持续数小时且MRI和脑电图无异常发现，他被诊断为短暂性全面遗忘症（TGA）。发作约一年后，他再次出现遗忘症，仅持续20分钟。MRI弥散加权成像（DWI）显示右侧海马区有一个小的高信号，而脑电图无异常。我们诊断他为复发性TGA。该病例可能有意思的地方在于，两次TGA发作之间症状持续时间和MRI-DWI表现有很大差异。
