Surgical management of focal cortical dysplasia

Focal cortical dysplasia is a malformation caused by abnormalities of cortical development. It is characterized by no dysmorphic or ballon cells (type I), dysmorphic neurons witout or with ballon cells (type II). It is the main cause of pharmacoresistant epilepsy. The combination of clinical and neurophysiological findings provided by VEEG and MRI had lead to an improvement in the diagnosis and outcome of FCD. This paper describes our experience in the form of a retrospective study conducted on the patients affected by FCD who were treated in the Clinical Neurophysiology Service at University Hospital of Lille in France.
