Transient global amnesia (TGA) is a neurological syndrome with rather distinctive brain MRI features, namely hyperintense lesion in hippocampus on diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) sequences. Post-traumatic amnesia is another amnestic syndrome which can also show hyperintense lesions in brain MRI due to cytotoxic oedema caused by traumatic brain injury. We present a case of a patient with post-traumatic amnesia with a brain MRI image mimic of TGA.
短暂性全面遗忘症（TGA）是一种具有明显特征性脑 MRI 表现的神经综合征，即在弥散加权成像（DWI）和液体衰减反转恢复（FLAIR）序列上显示海马区高信号病变。创伤后遗忘症是另一种遗忘综合征，也可因创伤性脑损伤引起的细胞毒性水肿导致脑 MRI 上出现高信号病变。我们报告了一例创伤后遗忘症患者，其脑 MRI 图像类似于 TGA。
