EEG is an important diagnostic tool in cerebral tumors, useful to identify tumor-related ictal and interictal epileptiform abnormalities or slowings, to monitor antiepileptic treatment, and to address surgery. In this chapter we will discuss the general and specific characteristics of EEG in different cerebral tumors, with distinction among sites and types of lesion. Some considerations about the pathophysiological mechanisms underlying the EEG abnormalities and the EEG characteristics after surgery will be made at least
