Dysembryoplastic neuroepithelial tumor (DNET)


This case illustrates a relatively typical appearance of DNET, namely a high T2 signal lesion with a 'bubbly' appearance located in the temporal lobe and resulting in temporal lobe epilepsy. Typically these lesions do not have any enhancement, although a degree of enhancement is certainly recognized in a minority of cases. Usually patients are younger when they first present.
