An irregular heterogenous partially-enhancing mass, with cystic/necrotic components, is located medially in the left temporo-occipital and inferior parietal regions. This appears to be of intra-ventricular/subependymal origin, invading adjacent parenchyma, with extensive surrounding vasogenic oedema and mass effect. The left lateral ventricular atrium is severely compressed/replaced and displaced laterally, with obstructive dilatation of the temporal horn. Two vividly enhancing satellite nodules are located posterior to the main tumor mass, with the larger, apparently intra-ventricular occipital nodule demonstrating several prominent feeding vessels and adjacent pathologic ependymal enhancement. In addition, a remote peripherally-enhancing 10 mm diameter nodular tumour focus is interposed between the left cerebral peduncle and posterior cerebral artery.
