A very large mass arising from the left frontal lobe and crossing the corpus callosum is present with central areas of haemorrhage. Unfortunately the patient was unable to tolerate the whole scan (note the movement degraded T1 sequence) and no contrast was thus administered.
This case illustrates typical non-contrast appearances of a WHO grade IV glioma, in this case a glioblastoma arising from an oligoastrocytoma.
Note: In a case of a glioblastoma arising from a pre-existing lower grade tumour, it would likely be IDH mutated. This case, however, predates the recent (2016) revision WHO classification of CNS tumours and IDH status is not available. As such, this tumour would now be classified as a glioblastoma NOS.
