Overview
CT
Head CT scan may be helpful in the diagnosis of oligodendroglioma.
Findings on CT scan suggestive of oligodendroglioma are listed below:[1]
- Round or oval sharply marginated mass involving the cortex or subcortical white matter
- Hypodense to isodense
- 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 material administration
Gallery
-
Heterogeneous region of contrast enhancement, edema and mass effect is present in the left frontal lobe.[2]
-
Right temporal hypodense space occupying lesion which contains internal central calcifications.[3]
-
Oligodendroglioma that is highly calcified.[4]
