The patient remained well until September 2009, when he was presented with a visual aura, and an urgent MRI scan showed that the primary tumour continued to decrease in size, but that there was an additional 27-mm enhancing extra axial lesion in the right frontal lobe, appearing to arise from the dura just adjacent to the burr hole site from the previous biopsy (Figure 2).
