Oligodendroglioma NOS

Case contributed by Dr Paresh K Desai



Patient Data

Age: 30 years
Gender: Male

A heavily calcified right frontal lobe mass. 


Single MRI image demonstrates only minor loss of signal due to calcium. 

Case Discussion

The patient had surgery which confirmed the diagnosis of oligodendroglioma.

MRI is a poor modality to pick up calcification. In the present case thought the mass is heavily calcified on CT; it is extremely difficult to predict on MR

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 oligodendroglioma NOS.
