Status epilepticus overnight, EEG showing periods of overactivity not consistent with high dose benzodiazepine therapy. There is vasogenic edema in the bilateral occipital, parietal, superior frontal, and posterior temporal lobes, with a few punctate foci of susceptibility effect in the bilateral parietal lobes. There is minimal T2 hyperintensity in the pons. There is no evidence of mass or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Findings most compatible with posterior reversible encephalopathy syndrome and associated microhemorrhages.
