Overview

CT

Head CT scan is helpful in the diagnosis of glioblastoma. On head CT scan, glioblastoma is characterized by:[1]

  • Irregular thick margins: iso to slightly hyper-attenuating
  • Irregular hypodense centre representing necrosis
  • Marked mass effect (midline shift)
  • Butterfly shaped mass crossing midline via the corpus callosum
  • Surrounding vasogenic edema
  • Hemorrhage
  • Calcification is rare
  • Intense irregular, heterogenous enhancement of the margins
