Presentation
Headache, neck pain and altered sensation in both upper limbs
Patient Data
This MRI brain demonstrates a right frontal lobe lesion which is T1 hypo-intense and T2 hyper-intense. It is mildly enhanced with contrast. Also noted midline shift to the left.
Case Discussion
The patient underwent right frontal craniotomy and debulking of the right frontal tumor. Histology showed oligodendroglioma WHO grade II.
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.
