case_images: Preoperative MRI of the lumbar spine: (a) sagittal plane T2-weighted image. (b) Axial plane T2-weighted image. The ventral dural line was divided such that disc herniation existed between the two lines (black arrow) (a). The border of cauda equina and disc herniation was unclear (b).

case_images: T2-weighted sagittal image (Figure 1(a)). The ventral dural line was divided into two near the disc herniation such that the herniation existed between these lines. The cauda equina was compressed by the disc herniation on T2-weighted axial images (Figure 1(b)).
case_images: Intraoperative ultrasonography. Disc herniation was discovered in the dura (white arrow).

case_images: We identified a disc herniation in the dura with an ultrasonography (Figure 2).
case_images: Intraoperative photograph. We identified the lumbar disc herniation covered with the arachnoid.
