Dysembryoplastic Neuroepithelial Tumor

Dysembryoplastic neuroepithelial tumor. Extensive myxoid change and disposition of small, oligodendrocyte-like cells along axonal fiber bundles and capillaries lend an alveolar or ‘patterned’ appearance to the specific glioneuronal element of this distinctive lesion. Not shown here, mature neurons often appear to float in the mucoid matrix.
