Magnetic resonance imaging (MRI) images with the right lateral epidural abnormality in the mid-thoracic spine with spinal cord compression. (a) Sagittal T2 sequences, (b) sagittal short-tau inversion recovery sequences, (c) sagittal T1 sequences without contrast, (d) sagittal T1 sequences with contrast, (e) axial T1 MRI with contrast demonstrating extension of a tophus into the spinal canal and compressing the spinal cord to the left, (f) axial T1 magnetic resonance imaging with contrast at a level with no inflammatory or degenerative changes and no spinal cord compression.

T2 enhancing epidural lesion extending from T6 to T8 contributing to severe canal/cord stenosis and mild cord T6-T9 cord edema [Figure 1a-f]. The noncontrast thoracic computed tomography scan demonstrated multilevel periarticular lytic/erosive lesions involving the T6-T7 to T8-T9 facet joints, accompanied by lobulated high-density juxta-articular material extending into the adjacent canal [Figure 2a-e].
Computed tomography (CT) images showing lytic process of bilateral thoracic facet joins with compression of the spinal cord. (a) Sagittal CT scans of the mid-thoracic spine demonstrating erosive changes of the right facet joints, (b) sagittal STIR sequences, (c) sagittal T1 sequences without contrast, (d) sagittal T1 sequences with contrast, (e) axial T1 magnetic resonance imaging with contrast demonstrating extension of a tophus into the spinal canal and compressing the spinal cord to the left.

(a) Postoperative anteroposterior and lateral thoracic X-rays demonstrating a short T6-T9 fusion construct. (b) Postoperative lateral X-rays of the thoracic spine demonstrating short fusion of the thoracic spine.
