The advent of MRI enables us to make an in-vivo diagnosis of cortical dysplastic lesions which are highly epileptogenic and show the variety of seizure patterns. Authors report a case of rolandic cortical dysplasia who had highly intractable focal motor clonic seizures. Invasive recording with subdural grid was very helpful in delinating the epileptogenic area as well as in function mapping of eloquent areas. Total removal of dysplastic lesion could treat this highly intractable epilepsy succesfully.
