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

* Butterfly shaped mass crossing midline via the corpus callosum
* Intense irregular, heterogenous enhancement of the margins
* Irregular hypodense center representing necrosis
* Marked mass effect (midline shift)
* Surrounding vasogenic edema
* Hemorrhage
* Calcification is rare
