Figure 1: Computed tomogram, sagittal reconstruction, shows the lytic lesion in the 11th dorsal vertebral body (a). Magnetic resonance imaging T1-weighted axial (b), T2-weighted sagittal (c), and T1-weighted-contrast (d), showing a heterogenously enhancing lesion involving the vertebral body with extension into the spinal canal compressing the cord. Histopathology images showing nodular deposits of amyloid surrounded by lymphoplasmacytic infiltrate (e) with apple-green bifringence under polarized light (f). Postoperative follow-up gadolinium enhanced magnetic resonance imaging showing the decompressed cord with implant in situ (g and h)
