Overview
CT findings
CT scan may be helpful in the diagnosis of astrocytoma. Findings on CT scan suggestive of astrocytoma include:[1]
- In low grade astrocytoma:
- Poorly demarcated mass
- Low density
- No inhancement inside the tumor
- In few cases we might see some calcification and cystic changes inside the mass
- In high grade astrocytoma:
- Poorly demarcated mass
- Low density
- There are partial enhancement inside the tumor mass
