In this review article, we present general information regarding potentialcauses of drug-resistant epilepsy and structural brain evaluation inepileptology using magnetic resonance imaging. The different types ofepileptogenic lesions of focal cortical dysplasia and findings in temporallobe epilepsy are summarized. The article includes chapters addressing theprocess of visual assessment of MR images in patients with epilepsy.

Keywords: epilepsy, focal cortical dysplasia, magnetic resonance imaging,mesial temporal sclerosis, structural brain imaging
