Regression of intervertebral disc calcification combined with ossification of the posterior longitudinal ligament: A case report

Figure 1 Digital radiography on admission. A and B: Digital radiography showing a dense projection of the intervertebral disc between the second and third cervical vertebrae.

Figure 2 Computed tomography on admission. A: Sagittal computed tomography revealing cervical disc calcification (orange arrow); B: Axial computed tomography further demonstrating cervical disc calcification (orange arrow) and partial ossification of the posterior longitudinal ligament (black arrow).

Figure 3 Magnetic resonance imaging on admission. Magnetic resonance imaging showing substantial spinal stenosis and spinal cord compression (orange arrow).

Figure 4 Computed tomography at the 3 mo follow-up. A and B: Follow-up computed tomography showing that only a small amount of calcification (orange arrow) and slight ossification of the posterior longitudinal ligament (black arrow) remain.
