Dysembryoplastic Neuroepithelial Tumor, Coronal section at the level of the parietal occipital junction.
On coronal surface, the tumor can be seen to be predominantly based within the cerebral cortical ribbon rather than in the underlying white matter. In addition the tumor is well demarcated from both the adjacent normal-appearing cortical ribbon and underlying normal-appearing white matter...

Dysembryoplastic Neuroepithelial Tumor, H&E stain
This photograph demonstrates the specific Glioneuronal element which characterizes the dysembryoplastic neuroepithelial tumor. Morphologically normal neurons appear to float in a background of oligodendroglia-like cells. Note the absence of perineuronal...

Dysembryoplastic Neuroepithelial Tumor, Ventral surface of brain, Close Up
Note the gelatinous expansion of the inferior temporal gyri with sharp demarcation from adjacent normal-appearing cerebral cortex.

Dysembryoplastic Neuroepthelial Tumor, Ventral surface of brain
The Dysembryoplastic Neuroepthelial Tumor appears as a gelatinous homogeneous region lacking normal cortical morphology, but also lacking evidence of peritumoral edema.
