Left hemiparesis and headache

Patient Data

Age: 78-year-old
Gender: Male

MRI Brain

Right parietooccipital irregular intra-axial heterogeneous lesion surrounded by perifocal oedema and exerting a positive mass effect on the ipsilateral lateral ventricle. It displays heterogeneous enhancement with a haemorrhagic component at the posterior aspect of this lesion.

Magnetic resonance spectroscopy reveals:

  • reduced NAA reflecting neuronal damage
  • elevated choline denoting rapid membrane turnover
  • marked lipid and lactate rise indicating intralesional necrosis

Case Discussion

The case was confirmed histologically.

Glioblastoma is a highly malignant primary brain tumour (WHO IV) and represents the most common primary malignant brain tumour.

Note: IDH mutation status is not provided in this case and according to the current (2016) WHO classification of CNS tumours, this tumour would, therefore, be designated as a glioblastoma NOS
