Glioblastoma multiforme comprises 15-20 % of all intracranial tumours. It makes a peak between the fifth and seventh decades of life but it is rare in childhood. One of the radiological and clinical properhes of glioblastoma multiforme is perifocal vasogenic oedema associated with the tumour. In the radiological evaluation of an 8 -yearold boy with glioblastoma multiforme, perifocal oedema did not accompany the lesion. The case is discussed with the cases in the literature.
