Preoperative radiographic images (A-F). (A,B) CT showed intervertebral disc herniation, loss of disc height, and osteophyte hyperplasia at the L2-L3 level. Sagittal T1-weighted (C) and T2-weighted (D) MRI revealed extruded intervertebral disc, and loss of continuity of the PLL at the L2-L3 level. (E,F) Axial T2-weighted MRI demonstrated the intradural mass.

L2-L3 level (Figures 1A,B). Lumbar magnetic resonance imaging (MRI) demonstrated that extruded intervertebral disc, loss of continuity of the PLL, and intradural masses at the L2-L3 level (Figures 1C-F).
Interoperative image revealed the extruded intervertebral disc.

There was a mass revealed disc-like substance in the dura sac (Figure 2).
Postoperative radiographic images (A-D). (A,B) MRI revealed that the extruded lumbar intervertebral disc was removed. (C,D) Plain radiographs showed interbody fusion with posterior instrumentation.

Postoperative radiographs revealed that the extruded intervertebral disc was removed and the position of internal fixation was good (Figure 3).
