Brain MRI (FLAIR) done during a typical PRES episode showing vasogenic edema in the parieto-occipital areas (A), resolved 3 months later (B). (C) A typical EEG obtained during an episode of PRES, demonstrating slowing of the background rhythm to 3–4Hz and posteriorly dominant independent bilateral PLEDs occurring at a frequency of about 1Hz. The two populations of PLEDs show distinct morphologies (with higher amplitude over the left hemisphere) and slightly different frequencies.
