There is a large, ill-defined hypo-attenuating area with loss of gray-white matter differentiation involving the right cerebral hemisphere with an irregular hyper-attenuating area of blood density within and also extending to the right lateral ventricle. Right proximal MCA is hyper-attenuated: “Hyperdense MCA”.
The significant mass effect is evidenced by the effacement of the ipsilateral Sylvian fissure, adjacent cortical sulci, lateral ventricle with midline shift toward the contralateral side. Subfalcine herniation also noted.
