Summary
A lumbar discal cyst causing severe leg pain was successfully removed surgically. This rare condition, potentially arising from disk injury and bleeding, resolved immediately post-operation.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Orthopedic Surgery
Background:
- Lumbar radiculopathy can be caused by various spinal pathologies.
- Discal cysts are rare and can present with significant neurological deficits.
Observation:
- A 25-year-old male presented with refractory left lumboischialgia and progressive L5/S1 radiculopathy.
- MRI revealed L4-5 discal cyst with osteolytic changes and L5-S1 disk herniation.
- Intraoperative findings included bloody and clear serous fluid during cyst resection.
Findings:
- Histological examination showed a fibrous cyst wall without cellular lining and fibrin deposits.
- Surgical resection of the cyst and herniated disk led to immediate symptom resolution.
- The osteolytic lumbar discal cyst is hypothesized to form from hemorrhage and subsequent encapsulation.
Implications:
- This case highlights a rare cause of lumbar radiculopathy.
- Surgical intervention is effective for symptomatic osteolytic lumbar discal cysts.
- Understanding the cyst's pathogenesis may aid in future diagnosis and management.
