MRI abnormalities such as thickening of the cortex and dysgyria, which could be considered as CD. Mild atrophy of the right hemisphere was also noted (Fig. 1).
Neurophysiological findings (invasive recording). (A) Interictal intermitted delta activity in the medial part of the right parietal lobe. Disorganization of background activity in the medial part of the right temporal lobe. (B) Ictal activity: low-amplitude fast activity in the medial part of the right temporal lobe (Td, 1-2 : arrow) and the following sharp-wave activity in the medial part of the left parietal lobe and depression of background activity in the medial part of the left temporal lobe.

Ictal onset was characterized by the appearance of fast activity in the right medial temporal regions followed by the rapid spreading of epileptic discharge to the left hemisphere (Fig. 2).
Postoperative MRI. Volume of surgical intervention (described in the text of the article).
