There is a large intra-axial mass of right occipitoparietal location, extending through the adjacent craniotomy. It appears spontaneously iso-to hyperdense to the cortical grey matter with homogeneous vivid enhancement except for the central hypodense necrotic areas (probably post-biopsy). The adjacent portion of the superior sagittal sinus is most likely invaded. Surrounding vasogenic oedema is noted as well as a mass effect on the right trigone with midline shift.
