Table 2.

Outcome of SEEG investigation and surgical outcome of the patients according to MEG spiking volume

MEG SV	SEEG		Surgery		SEEG congruence
	Non-localized n (%)	Localized n (%)	Good outcome n (%)	Poor outcome n (%)	Lateralized-epileptogenic zone (%)	Non-lateralized- epileptogenic zone (%)
Focal	0 (0)	8 (100)	6 (86)	1 (14)	65	35
Lateralized	4 (57)	3 (43)	0 (0)	2 (100)
Non-lateralized	2 (100)	0 (0)	0 (0)	2 (100)

Good outcome = number (percentage) of patients with Engel Score I; poor outcome = number (percentage) of patients with Engel Score other than I.

EZ = epileptogenic zone; SV = spiking volume.
