CT findings

CT scan may be helpful in the diagnosis of astrocytoma. Findings on CT scan suggestive of astrocytoma include:

• 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
