[Temporal post-traumatic epilepsy: corticographic and ultrastructural study of a case].

A case of post-traumatic temporal epilepsy, submitted to a temporal lobectomy, is reported. During surgery, electrocorticography was carried out in order to differentiate epileptic areas from normal tissue. The ultrastructural study of nervous tissue removed from both normal and epileptogenic areas showed diffuse and aspecific process of neuronal alterations without a correlation to the electrographic epileptic areas. The importance of trauma in the evolution of these alterations is discussed.
