T2/FLAIR hyperintense mass in right frontotemporal lobe involving cortex and subcortical white matter with areas of heterogeneous contrast enhancement.
The patient underwent a right frontotemporal craniotomy and subtotal tumor resection. Histology demonstrated an 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 oligodendroglioma NOS.
