Abstract
Dysembryoplastic neuroepithelial tumors (DNTs) are mainly benign cortical lesions composed of glial and neuronal elements. DNTs accounted for 0.6-07% of pediatric brain tumors. Clinically these tumors are usually associated with chronic epilepsy in adolescents and adults. We report a case of six-year-old boy who presented drug-resistant complex partial seizures whit neurological and intellectual integrity, but a mild attention deficit. MRI disclosed a subcortical lesion, located on the left the temporal lobe. The pathological tissue was hyperintense on both T1 and T2-weighted images; CT showed very well intratumoral calcifications. These neuroradiological findings suggested a differential diagnosis with extraventricular neurocytoma and ganglioglioma. The child underwent surgery; the histological examination diagnosed a complex DNT (1st grade of WHO classification). At follow-up after 6 months, he was seizure-free; the neurological examination was normal.
