Abstract:
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.

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
