Overview
CT
- Oligodendrogliomas typically manifest as a round or oval sharply marginated mass involving the cortex or subcortical white matter at cross-sectional neuroimaging.
- At computed tomography, about 60% are hypoattenuating while 23% are isoattenuating and about 6% are hyperattenuating.
- Calcification is noted in 20%–91% of cases.
- Subtle ill-defined enhancement following intravenous contrast material administration is seen in 15%–20% of oligodendrogliomas and is associated with higher-grade tumors.
