Introduction: to determine the lateralization of lesion by non-invasive methods through correlation of cranial magnetic resonance imaging (MRI) and electroencephalography (EEG) findings in patients with mesial temporal sclerosis (MTS).


Methods: This study included 40 patients (Age range, 19 to 55 years) among 1850 patients who were attending outpatient epilepsy clinic of Haydarpaşa Numune Hospital between the years 2000-2013. Exclusion criteria were surgery due to MTS, metabolic and systemic disorders, indefinite diagnosis, and inadequate MRI and EEG evaluations.


Results: EEG findings were within normal limits in 10 (25%) patients who had mesial temporal sclerosis on MRI. Of these, 5 patients had right MTS, 4 patients had left MTS, and one patient had bilateral MTS.


Conclusion: In this study, we used electrophysiological diagnostic methods together with MR imaging to determine epileptogenic localization in patients with mesial temporal sclerosis. We suggest that when correlated with MRI, EEG is a non-invasive, easy method to identify lateralization findings.
