From the case:
Glioblastoma NOS (gross pathology)
Coronal section Gross pathology

Tumor measuring 9x8x7cm in the left temporal lobe with central necrosis and hemorrhage. Subfalcine herniation to the right side.
Case Discussion
Glioblastoma diagnosed 2 years prior to eventual death due to aspiration pneumonia.
Note: IDH mutation status is not provided in this case and according to the current (2016) WHO classification of CNS tumors, this tumor would, therefore, be designated as a glioblastoma NOS.
