Overview
CT scan may be helpful in the diagnosis of astrocytoma. Findings on CT scan suggestive of astrocytoma include: Poorly demarcated mass, low density and no inhancement inside the tumor In low grade astrocytoma, poorly demarcated mass, low density and there are partial enhancement inside the tumor mas In high grade astrocytoma.
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
