Overview
On head CT scan, ganglioglioma is characterized by iso- or hypodense, calcification, bone remodelling, and enhancement of non-calcified component.
CT
Head CT scan is helpful in the diagnosis of ganglioglioma. Partially cystic mass with an enhancing mural nodule is seen in 45% of cases. They may also simply present as a solid mass expanding the overlying gyrus. An infiltrating mass is uncommon and may reflect higher grade.[1]
On head CT scan, ganglioglioma is characterized by:
- Iso- or hypodense
- Frequently calcified ~35%
- Bone remodeling or thinning (indicates the slow growing nature of the tumor)
- Enhancement in 50% of cases (involving the solid non-calcified component)
