Dysembryoplastic neuroepithelial tumour, MRI FLAIR.

Dysembryoplastic neuroepithelial tumour, commonly abbreviated DNT or DNET, is a type of brain tumour.

Defined as "an usually supratentorial glial-neuronal neoplasm occurring in children and young adults and characterized by a predominantly cortical location and by drug-resistant partial seizures" [1]

It appears similar to oligodendroglioma, but with visible neurons.[2]

It is a benign tumor (Grade I of the WHO classification of brain tumours).[3][4]

It can cause epilepsy.[5]

Treatment[edit]

Treatment of DNTs is usually surgical resection.[6]
