The specimen shows a large intracerebral lesion, which has obliterated the lateral ventricles and the inner 2/3 of the internal capsule and basal ganglia on the right side. It is infiltrating across the corpus callosum and distorting the aqueduct. The tumour is fairly well demarcated and vascular with numerous areas of haemorrhage and necrosis, causing its mottled variegated appearance.
