Head CT scan may be helpful in the diagnosis of oligodendroglioma. Findings on CT scan suggestive of oligodendroglioma are round or oval, marginated, hypo- to isodense mass with hemorrhage, ribbon-like calcification, ill-defined enhancement following intravenous contrast administration, pressure erosion/remodelling of overlying skull, and marked ventricular enlargement suggestive of hydrocephalus.

• Head CT scan may be helpful in the diagnosis of oligodendroglioma
• Findings on CT scan suggestive of oligodendroglioma are listed below:^{[1][2][3][4][5]}
  • Round or oval, sharply marginated mass involving the cortex or subcortical white matter
  • Hypodense to isodense mass
  • Hemorrhage
  • Overlying skull may show pressure erosion/remodelling
  • Calcification (70-90%)
    • Located centrally or peripherally
    • May be ribbon-like
  • Ill-defined enhancement (50%) following intravenous contrast administration
  • Marked ventricular enlargement suggestive of hydrocephalus
