Seizures.
Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
Note: The diagnostic criteria reflect practice at the time and do not necessarily match the current WHO classification of CNS tumors.
A mass which involves the cortex is present within the left frontal lobe. it demonstrates wispy heterogeneous contrast enhancement and moderate restricted diffusion. Some areas of signal loss likely represent calcification.
Case Discussion
This patient went on to have a craniotomy which confirmed the diagnosis of an anaplastic 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 grade 3.
