Figure 5

Example of nSVZE. A 66-year-old male with pathologically confirmed anaplastic astrocytoma in the left parieto-occipital lobe. His OS was 510 days. Axial contrast-enhanced T1-weighted image 72 h after resection (a). Axial contrast-enhanced CT image with treatment-planning overlay shows the volumes treated with 60 Gy (blue outline) and 50 Gy (red outline) (b). There was nSVZE lesion at the left trigonum in follow-up MRI 6 months after completion of radiotherapy (c). nSVZE, new subventricular zone enhancement.
