Summary
This study reports a rare case of intraspinal choristoma, a benign tumor. Surgical removal led to complete symptom relief, highlighting the importance of considering this rare spinal tumor in diagnosis.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Choristomas are rare benign neoplasms of normal tissue in abnormal locations.
- Intraspinal choristomas are exceptionally rare, with only four prior cases documented.
- Diagnostic challenges arise due to their complex composition and rarity, often missed by routine imaging.
Observation:
- A 48-year-old female presented with chronic lower back pain and radiating leg pain.
- Magnetic resonance imaging revealed an intradural space-occupying lesion at L1.
- Enhanced magnetic resonance neurography was performed for surgical planning.
Findings:
- Postoperative pathological biopsy confirmed the lesion as an intraspinal choristoma.
- This case featured a choristoma lacking specific tissue components, increasing diagnostic difficulty.
- Surgical excision of the intradural extramedullary spinal choristoma was performed.
Implications:
- Complete symptom resolution and no recurrence after 1 year of follow-up.
- Intraspinal choristomas require pathological examination for definitive diagnosis due to non-specific presentation.
- Early detection and intervention for intraspinal tumors are crucial to prevent neurological deficits.
