Cranial MRI examination of a nine-year-old male showing ADEM-like signal changes without diffusion restriction (a-c) in the cerebellar hemispheres, periaquaductal region, mesencephalon, bilateral hypothalamic region, bilateral thalamus, lentiform nucleus, caudate nucleus and deep white matter and subcortical area . Cranial MRI performed five days after the seizure recurred indicates that the lesions have completely disappeared, but there are new pathological signal changes in bilateral parietooccipital region and bilateral frontoparietal region, which do not show contrast enhancement or diffusion restriction. These new lesions were evaluated as PRES.
