Dysembryoplastic neuroepithelial tumors (DNETs) are frequently seen in children and young adults with intractable epilepsy, and are typically located in the temporal cortex. Extracortical location of DNET is a very rare occurrence. The authors report on a child with a unique extracortical location of DNET with an extensive involvement to the supracallosal cistern and callosum, septum pellucidum, and lateral ventricle ependyma. The authors discuss the radiological and pathological characteristics of the lesion and reiterate the difficulty in differentiating the histological characteristics of central neurocytoma and DNET in extracortical locations and its significance for further management planning.
