case_images: Right lateral pre-operative radiograph showing smooth periosteal proliferation from the ventral margin of the L3 vertebral body, as well as an ill-defined increase in mineral opacity centrally. The L3 vertebral body has a mildly moth-eaten lysis caudally. The yellow arrow indicates L3.

case_images: The lysis did not affect the lamina or pedicle of the vertebra (Figure 1).
case_images: Transverse (A) and (B), and coronal (C) CT images. There were multiple punctate hypoattenuating defects within the L3 vertebral body that coalesced caudally into a zone of moth-eaten lysis. There was a fluffy periosteal reaction ventrally, with multiple focal regions of cortical loss. The yellow arrow indicates L3.

case_images: On the post-contrast scan, there was a long, crescent-shaped zone of contrast enhancement within the ventral spinal canal, dorsal to L3, causing mild extradural compression of the cord (Figure 2).
case_images: Immediate postoperative right lateral (A) and ventrodorsal (B) radiographs of the thoracolumbar spine. The images show that the two 10-hole String of Pearls (SOP ) plates were applied to the right and left dorsolateral aspects of the vertebral bodies. Note that the first screw on the left plate did not engage the cortex of L1. This configuration resulted in one screw engaging the body of L1, four in the bodies of L2 and L4, and two screws engaging the body of L5. The articular facets and spinous process of L3 remained in the appropriate location and were static. A metallic hemoclip was superimposed over the spinal canal on the ventrodorsal projection at the level of cranial L3. There was an irregularly shaped, curvilinear new bone where the body of L3 was removed. The dorsal aspect of the iliac wings was irregular with flattened irregular margins, consistent with ostectomy. The yellow arrow indicates L3.

case_images: Postoperative lateral and dorsoventral radiographs were performed and showed screw placement and positioning of the bone graft, as shown in Figure 3.
case_images: Right lateral (A) and ventrodorsal (B) radiographs of the thoracolumbar spine 2 months postoperative showing the static L3 corpectomy with the stabilization of the spine using two SOP  plates and associated screws. No evidence of implant failure/loosening was noted. The mineral opacity in the location of L3, as well as the ostectomy of the iliac wings, was consistent with a remodeling bone graft. The yellow arrows indicate L3.

case_images: Oncological Services for further assessment. Spinal radiographs showed no evidence of implant failure or loosening at this time, and no evidence of bone lysis was appreciated. Osseous integration of the cortico-cancellous autograft was noted at this time (Figure 4).
