An image is not always worth a thousand words: an image mimic of transient global amnesia

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...

More Information
Summary: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.
