Whole head magnetoencephalography (MEG) systems facilitate simultaneous recording from the entire brain surface and deep structures. Thus MEG may be accepted as a clinically feasible method for the evaluation of epileptic patients not diagnosed with EEG. A 11 year old female, with tonic generalized seizures since birth. At the present time, seizures consist of initial focal signs followed by fear sensation and both eyes and cephalic deviation to the right, tonic extension of the superior limbs and prolonged apnea. Complementary examinations (EEG, Holter EEG, Video EEG, CT, MRI, SPECT) were normal. MEG study was conclusive, diagnosing sharp waves in the internal face of the left precentral circunvolution. MEG study s utility in seizures focus localization and pseudo seizures differential diagnosis has been demonstrated.
