Abstract:
BACKGROUND: Mesial temporal sclerosis (MTS) is a well-known cause of temporal lobe epilepsy. Coexistence with cortical dysplasia (CD) has been reported, but its role is not well recognized. This study aims to determine whether there is any difference about clinical feature and surgical outcome between patients with MTS and coexistent CD (group 1) and patients with isolated MTS (group 2). METHODS: Retrospectively, surgical series of 45 patients (male:22, female:23) diagnosed as temporal lobe epilepsy were reviewed. We excluded patients who had another pathology (e. g., tumor, vascular malformation) except MTS or CD. The pathology, case histories, interictal EEG, and surgical outcome were compared. RESULTS: There was a tendency for group 1 patients to have earlier seizure onset age (10.9+/-6.35 versus 14.5+/-6.03, p=0.06) There was no statistically significant difference in the history of febrile convulsions (68.4% versus 53.8%, p>0.16) No statistically significant difference between groups were also found in disease duration, the head trauma/mental retardation history, seizure frequency, interictal EEG, and surgical outcome. CONCLUSIONS: CD in MTS appears to have an influence on seizure onset. The relationships among CD, febrile convulsion, and mesial temporal sclerosis must be more investigated.
