Large mixed solid and cystic mass arising in the right frontal lobe and extending into subcallosal region causing an upward displacement of the genu of corpus callosum. The solid component is isointense in relation to the grey matter. There is mass effect on anterior horns of lateral ventricle and 10 mm leftward shift.
There is moderate peritumoral oedema that extends into the insular subcortical white matter. The anterior commissure deviated posteriorly due to the mass effect.
GRE hypointensities are suggestive of calcifications or blood products. There are DWI hyperintense signals suggestive of hypercellularity.
There is homogeneous enhancement of the solid component of the tumour and marginal enhancement surrounding the cystic components as well.
