Oligodendroglioma NOS

Case contributed by Frank Gaillard
Diagnosis almost certain

Presentation

Partial seizures described as episodic LOC preceded by an olfactory aura.

Patient Data

Age: 20 years
Gender: Female
mri

T2/FLAIR hyperintense mass in right frontotemporal lobe involving cortex and subcortical white matter with areas of heterogeneous contrast enhancement.

Case Discussion

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.
