3. Axial computed tomographic scan demonstrating that the prolapsed calcification located eccentrically occupies over half of the spinal canal space and extends beyond the midline. Xiao-Dong Wu et al. J Bone Joint Surg Am 2010;92:1992- 1996 ©2010 by The Journal of Bone and Joint Surgery, Inc.

4. A T2-weighted sagittal magnetic resonance image demonstrates marked compression of the dural sac and spinal cord due to a large extradural mass of very low signal intensity at the T2-T3 level.

5. Axial computed tomographic scan, made at the six-month follow-up evaluation, demonstrating complete resolution of the calcification in the spinal canal, with mild resorption of the calcification within the intervertebral disc.
