Association of Lateralized Interictal Epileptiform Discharges with Postsurgical Seizure Outcomes in Patients with Tuberous Sclerosis Complex: A 10-Year Retrospective Study at a Single Center

Table 6

The relationship between IED patterns and imaging features in TSC patients.

IED patterns	Cyst		Calcification		SEN		SEGN
	Yes	No	Yes	No	Yes	No	Yes	No
Focal	3 (25)	9 (75)	3 (25)	9 (75)	11 (91.7)	1 (8.3)	4 (33.3)	8 (66.7)
Lateralized	5 (16.1)	26 (83.9)	6 (20.7)^a	25 (79.3)	27 (87.1)	4 (12.9)	10 (32.2)	21 (67.7)
Multifocal	3 (21.4)	11 (78.6)	4 (28.6)	10 (71.4)	12 (85.7)	2 (14.3)	4 (28.6)	10 (71.4)
Generalized	7 (28)	18 (72)	14 (56)	11 (44)	21 (84)	4 (16)	7 (28)	18 (72)

Abbreviations: IEDs: interictal epileptiform discharges; TSC: tuberous sclerosis complex; SEN: subependymal nodules. Values are (%). ^a, the percentage of patients with calcified tubers versus the data in the generalized group.
