Utility of electrocorticography in the surgical treatment of cavernomas presenting with pharmacoresistant epilepsy.

Aim: To describe the general aspects of cavernomas and epilepsy and review the available literature on the utility of electrocorticography (ECoG) in cerebral cavernoma surgery.

Methods: We searched studies in PubMed, MedLine, Scopus, Web of Science, and Google Scholar (from January 1969 to December 2013) using the keywords "electrocorticography" or "ECoG" or "prognosis" or "outcome" and "cavernomas". Original articles that reported utility of ECoG in epilepsy surgery were included.
