Preoperative sagittal T2-weighted MRI from sagittal view showed disc herniation at L3/4 disc level (a), and MRI from axial views showed left side huge herniation occupying the spinal canal (b-d).

Magnetic resonance imaging (MRI) and computed tomography (CT) after discography revealed a large disc herniation at L3/4 on the left side that was occupying 75% of the volume of the spinal canal (Figure 1).
The first postoperative T2-weighted MRI did not change disc herniation at L3/4 disc level (a), and trajectory did not reach disc herniation (b-d).

The surgery was immediately stopped, and emergency MRI showed that the size of the herniation had not changed and that the endoscope did not reach the herniated mass (Figure 2).
The latest postoperative T2-weighted MRI showed the removal of the nucleus pulposus and distension of the dura mater (a-d).

MRI confirmed removal of the nucleus pulposus and showed distension of the dura mater (Figure 3).
