Anaplastic oligodendroglioma NOS

Case contributed by A.Prof Frank Gaillard

Presentation

Seizures.

Patient Data

Age: 50 years
Gender: Female
MRI

MRI brain

A large mass in the right temporal lobe demonstrates central regions of non-enhancement with peripheral heterogeneous enhancement. There is extensive involvement of the overlying cortex and the solid components demonstrate restricted diffusion. 

Case Discussion

The patient went on to have surgery and histology revealed the lesion to be an anaplastic oligoastrocytoma.

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