Abstract
- Three patients with complex partial seizures had dysembryoplastic neuroepithelial tumor (DNET) in temporal lobe. In all cases, longterm video-EEG monitoring showed epileptogenic focus in left temporal lobe where small mass lesion was located. For further seizure localization and functional mapping, subdural grids were placed on left temporal lobe including lesions. Lateral temporal lobectomy with lesionectomy was performed in two cases. Lateral temporal lobe resection and amygdalohippocampectomy was done in one case. The pathological findings of all lesions were characterized by intracortical location, multiple nodular architecture, foci of dysplastic cortical disorganization and the presence of a specific glioneuronal element. All patients have been seizure free.
