T1 weighted and hyperintense on T2 weighted sequences (Figure 1). This disease presentation corresponded to Kadish stage B.
Axial (a, b), coronal (c) and sagittal (d) views of target volumes: inner lines correspond to clinical target volume, whereas outer lines represent planning target volume

A 5-mm isotropic margin was added to the CTV to obtain the planning target volume (PTV) (Figure 2).
Dose distribution in axial (a, b), coronal (c) and sagittal (d) CT planning slices: the inner line corresponds to the planning target volume, whereas the other lines going outwards represent 95, 80 and 50% isodoses, respectively
