Dysembryoplastic neuroepithelial tumour, MRI FLAIR.

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

It appears similar to oligodendroglioma, but with visible neurons.[1]

It falls into Grade I of the WHO classification of brain tumours and, generally, has a good prognosis.[2][3]

It can cause epilepsy.[4]

Treatment

Treatment of DNTs is usually surgical resection.[5]
