Overview
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, calcification, and ill-defined enhancement following intravenous contrast administration.
CT
- 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
- 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
