Glioblastoma NOS

Discussion:

Finally, the patient consented to surgery. Histology demonstrated a glioblastoma (GBM).

It is uncommon to watch a brain tumor grow for 5 years, but when complicated psychosocial issues are present following up patients or convincing them to have treatment can be difficult. 

Note: This case predates the recent (2016) revision WHO classification of CNS tumors and IDH status is not available. Although with such a protracted documented history this is likely a secondary GBM and thus likely IDH mutated, as this has not been established this tumor would now be classified as a glioblastoma NOS.
