2. Fig. 1
Periodic lateralizing epileptiform discharges (PLEDs). A, EEG tracings demonstrate PLEDs in left temporal area (upper four tracings) and right temporal area (lower four tracings). Lowest tracing on the right shows crossover effect from the left hemisphere. B, EEG tracings in the same patient 5 days later show resolution of PLEDs.

Series of head CT scans in patient with cerebral hyperperfusion syndrome. A, Nine days before carotid endarterectomy, normal scan. B, Five days after endarterectomy at time of seizure, showing diffuse patchy edema consistent with hyperperfusion. C, Eight weeks after endarterectomy, with resolution of edema.
