There is an infiltrative mass encasing the occipital horn of the left lateral ventricle, crossing the splenium of the corpus callosum, extending into the left temporal lobe and into the left cerebral peduncle. There is a necrotic enhancing area demonstrating thick peripheral enhancement in the posterior temporal region.
There is mass-effect with 9 mm midline shift, distortion of the brainstem and effacement of the cortical sulci.
