Case Discussion

This patient went on to have a craniotomy which confirmed the diagnosis of an anaplastic oligodendroglioma.

Note: This case predates the recent (2016) revision WHO classification of CNS tumors, and thus molecular markers (IDH mutation and 1p19q co-deletion) are not available. As such, this tumor would now be classified as an anaplastic oligodendroglioma NOS.
