Seizures.
Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
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 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.
