A brain RMN showed non-specific meningeal FLAIR hyperintesity (Fig. 1A-B).
A. EEG showing excessive beta activity and generalized spike and wave discharges, sometimes with left-sided parasagittal predominance, and others with right-sided parasagittal predominance. This EEG was recorded before antiepileptic treatment was started.B. EEG 4 days after initiating valproate showing excessive beta activity and no spike and wave discharges. C. Normal EEG one year later, under treatment with valproate, showing no beta activity. High pass filter 0,5 Hz, low pass filter 70 Hz.

An electroencephalogram (EEG) displayed increased in beta rhythms and generalized epileptogenic activity (Fig. 2A). A control EEG two weeks later showed persistence of beta alternating with physiological Alpha rhythms but no epileptogenic activity (Fig. 2B). Control EEG and RNM were normal (Fig. 2C and Fig. 1C-D, respectively).
