CT

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

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