Table 4.

Distribution of the main findings of visual MRI analysis and the level of significance in relation to the seizure occurrence.

Variables. n (%)	Patients with uncontrolled seizures	Patients with seizure control	P-value
Patients (n = 22)
Perilesional gliosis	13 (68.42)	6 (31.57)	0.963
Perilesional edema	14 (87.5)	2 (12.5)	0.004
Contrast enhancement	10 (71.42)	4 (28.57)	0.510
Hippocampal atrophy with other signs of HS.	6 (75.00)	2 (25.00)	0.490
Diffuse cerebral atrophy	3 (100)	–	–
Ventricular dilatation	2 (100)	–	–

There was an association between perilesional edema and recurrence of seizures (p = 0.004; Fisher's test). Significant p-values are in bold.
