Figure 1

A 67-year-old man with known metastatic small cell lung cancer presents with interscapular back pain that is exacerbated by movement and relieved with rest. Computed Tomography (CT) (A: left parasagittal, B: midline parasagittal, C: right parasagittal, D: coronal, and E: axial) and Magnectic Resonance (MR) images (F: sagittal, T2-weighted) outline the key details of this T5 lesion. Total SINS score = Semirigid (T5) spine, 1 point; ‘Mechanical’ pain (yes), 3 points; Lytic lesion, 2 points; De novo kyphotic deformity without subluxation/translation, 2 points; >50% vertebral body collapse, 3 points; and bilateral posterolateral spinal element involvement, 3 points. Total SINS score = 1 + 3 + 2 + 2 + 3 + 3 = 14 (unstable, surgical consultation is recommended).
