16-year-old girl with history of posterior reversible encephalopathy syndrome and altered mental status. Cortical and subcortical areas of T2 hyperintensity from examination on 11/11/2016 have resolved. There are a few, residual foci of T2/FLAIR hyperintensity in the periventricular white matter, stable from 11/18/2016. There is no restricted diffusion to suggest acute ischemia. There is no intracranial hemorrhage. There is no intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. The major flow-voids are preserved. The orbits, paranasal sinuses, and calvarium are unremarkable.
Stable examination with small areas of residual signal abnormality but no evidence of recurrent PRES.
