right temporal: Dysembryoplastic neuroepithelial
Sections confirm a dysembryoplastic neuroepithelial tumor within the
mesial block. A low grade glial neuronal tumor is located within cortex and
white matter, and contains cystic elements. Floating neurons are observed.
Neurocytic-type cells are also noted. In addition to the dysembryoplastic neuroepithelial tumor, varying
degrees of cerebral microdysgenesis are also observed. This is represented by
small aggregates of neurons and neurocytic type cells, and increased numbers of
ganglion type cells within white matter. Mesial temporal sclerosis is not defined.
