CT without contrast demonstrates a very large hyperdense mass in the supratentorial compartment which has markedly heterogeneous density with components of fat, fluid and soft-tissue attenuation. Hyperdense material layers dependently in the occipital horns consistent with blood. 

Marked supratentorial obstructive hydrocephalus with transependymal CSF permeation.

MRI brain


MRI confirms the findings, with a large heterogeneous mass with variable signal and blood layering both within cystic components of the mass as well as in the occipital horns.
