"T1: often normal during acute illness, with increased cortical signal intensity indicative of cortical laminar necrosis appreciated later 2"
"T2/FLAIR: hyperintensity and swelling of the cortex 2-4"
"DWI: high signal regions in subcortical white matter, particularly in watershed zones indicative of acute infarction, but also in other patterns (e.g. bright tree appearance) 2-4"
"acute encephalopathy with biphasic seizures and late reduced diffusion (AESD)"
"Prognosis of haemorrhagic shock and encephalopathy syndrome is very poor, with at least one-third of patients across case series dying due to the illness 1,2. There is a high neurological morbidity in survivors of the condition 1,2."
