MRI examination of an 8-year-old post-allogenic HSCT patient presenting with convulsions and disturbed conscious. a & e axial FLAIR images revealing bilateral frontal, parietal, occipital (not shown in images), and cerebellar asymmetrical cortical and subcortical high FLAIR signal. b & f ADC maps showing bilateral frontal, parietal, and occipital high signal impressive of facilitated diffusion. c & g Contrast-enhanced axial image showing no evident post-contrast enhancement. The patient was diagnosed with posterior reversible encephalopathy syndrome (PRES). d & h Follow up axial FLAIR images showing total resolution of the previously noted altered cortical and subcortical signal with no residual changes
