case_images: Microscopic section of the vertebral bone lesion (haematoxylin and eosin).
  The lesion consists of proliferations of well differentiated blood vessels.
  Circles indicate capillaries; stars indicate arterioles and venules; and
  triangles indicate small trabeculae of lamellar bone

case_images: Figure 1 shows a microscopic section of the vertebral bone lesion described.
case_images: Transverse and sagittal CT view at the T5 vertebral lesion, highlighting the
  radiation therapy contour planning. The red circles denote the planning
  target volume; the pink circles denote the gross tumour volume; and the
  orange circles denote the clinical target volume

case_images: Figure 2 presents the gross tumour volume (GTV), the clinical target volume (CTV) and planning target volume (PTV) for the radiation course.
case_images: Comparative MRI images. Top images were obtained at the time of diagnosis
  (preoperatively and before radiation therapy). Bottom images were obtained
  at 6 months post-radiation therapy. (a) Transverse T2-weighted (T2W) at the
  level of T5 showing a moderate left-sided compression of the spinal cord by
  an heterogeneous extradural mass originating from the T5 vertebra. (b)
  Transverse T1-weighted (T1W) fat saturation (FAT SAT) image postcontrast at
  the level of T5, showing homogeneous contrast enhancement of the extradural
  mass. (c) Transverse T2W at the level of T5 showing a mild left-sided
  compression of the spinal cord by a heterogeneous extradural mass
  originating from the T5 vertebra and (d) Transverse T1W FAT SAT postcontrast
  image at the level of T5 showing no abnormal contrast enhancement of the
  extradural mass. The white arrow points at the extradural mass effect
  resulting from the thickened left vertebral pedicle of T5. Dr = dorsal;
  L = left

case_images: Transverse CT images and bone window at the level of the mid part of the T5
  vertebra (top images) and the caudal part of the T5 vertebra (bottom images)
  at different time points after radiation therapy. (a,f) At the time of
  diagnosis, prior to surgery, (b,g) 2 months postoperatively at the time of
  clinical relapse, (c,h) 3 months post-radiation therapy, (d,i) 6 months
  post-radiation therapy and (e,j) 19 months post-radiation therapy
