Dysembryoplastic neuroepithelial tumour—a case report

Dysembryoplastic neuroepithelial tumor (DNET) is a mixed glioneuronal tumour which is most commonly seen in the temporal lobe of children and young adults. The patients present with pharmacoresistant complex partial seizures. DNET closely resembles oligodendroglioma clinicopathologically but immunohistochemistry, with positivity of NeuN in neurons and small round cells, aids in the differential diagnosis, which is important as DNET has a better prognosis. We report a case of DNET in a 16 year old female who presented with complex partial seizures and a mass in the right frontal cortex.
