Abstract

Psychosis is the most severe psychiatric complication of epilepsy surgery, We report two cases of newly-developed psychosis after temporal lobectomy, First case is a 46-year-old man with mesial temporal lobe epilepsy who presented recurrent postictal psychosis 1 year after right temporal lobectomy. Second case is a 44-years-old woman who presented chronic psychosis 6 month after left temporal lobectomy. Main psychotic symptoms were paranoid persecutory delusion. The common features in both cases were middle age, ling duration of epilepsy, and bilateral independent spike on preoperative EEG. Even if postoperative psychosis is rare, careful observation is needed because temporal lobectomy is an ever-increasing treatment.
