"In addition to CHANTER syndrome and POUNCE syndrome, which most likely exist on a spectrum, the imaging differential for causes of bilateral hippocampal restricted diffusion includes hypoxic-ischaemic injury (e.g. cardiac arrest), seizures, cardioembolic infarcts, hypoglycaemic encephalopathy, and encephalitis 5. Transient global amnesia appears as punctate foci of restricted diffusion, rather than diffuse change."
