Summary
Intradural disk herniation (IDH) is rare, especially in the upper lumbar spine. This case highlights the need for microscopic surgery for safe IDH removal and dural repair, even if endoscopic surgery is initially planned.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Minimally Invasive Spine Surgery
Background:
- Intradural disk herniation (IDH) involves nucleus pulposus displacement into the dural sac, a rare lumbar spinal lesion.
- Upper lumbar IDH, such as at L2-L3, is exceptionally uncommon compared to lower lumbar levels.
- Traditional understanding of lumbar disc herniations primarily focuses on extradural occurrences.
