A 61 year old male who presented with an epileptic episode was evaluated. A temporo-parietal-occipito mass was detected on MRI and PET CT. A follow-up MRI one year later showed progression of the lesion. One month later he had a craniotomy and what seems to be a partial removel of the mass. The pathology revealed glioblastoma. He was scheduled for radiotherapy two months later. The post operative MRI showed post operative changes including blood at the surgical cavity. However, there is a significant residual tumor present which is enhancing following administration of contrast.
