Reader Response: Benefits and Risks of Epilepsy Surgery in Patients With Focal Cortical Dysplasia Type 2 in the Central Region.

I read the article by Chassoux et al.1 with interest, and I have some questions that may be outside the focus of their study. The authors described that resections were associated with minor/moderate deficits and total recovery was observed in 40% of patients. Did any of these patients have neurologic deficits before resections? For example, the patient demonstrated in the MRI images showed focal cortical dysplasia near the precentral knob. Injury to this area has been reported to show isolated motor palsy in the hand, mimicking a peripheral nerve palsy.2,3 Can the authors please comment on the neurologic findings of these patients?
