Case contributed by A.Prof Frank Gaillard

Patient Data

Age: 60 years
Gender: Female

MRI brain

Modality: MRI

A small subcortical region of high T2 signal is seen in the left frontal lobe.

The patient was lost to follow-up for 5 years and represented with a further seizure. A CT demonstrated an abnormality which prompted further MRI imaging. 

MRI brain - 5 years later

Modality: MRI

The region has increased in size and now vividly enhances. 

The patient refused treatment and again failed to attend follow-up visits. They were homeless and unable to be located. 6 months later they presented with increasing headaches and seizures. 

CT Brain - 6 months later

Modality: CT

A peripherally enhancing lesion is located within the left frontal lobe. 

Case Discussion

Finally, the patient consented to surgery. Histology demonstrated a glioblastoma (GBM).

It is uncommon to watch a brain tumour grow for 5 years, but when complicated psychosocial issues are present following up patients or convincing them to have treatment can be difficult. 

Note: This case predates the recent (2016) revision WHO classification of CNS tumours and IDH status is not available. Although with such a protracted documented history this is likely a secondary GBM and thus likely IDH mutated, as this has not been established this tumour would now be classified as a glioblastoma NOS.
