Migrated disc in the lumbar spinal canal--case report
Neurologia Medico-Chirurgica
|November 24, 1999
Summary
A migrated disc, a rare cause of intraspinal mass, can mimic tumors in patients with chronic back pain. Surgical removal of degenerated disc fragments relieved symptoms, highlighting its importance in differential diagnosis.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Neurology
Background:
- Chronic back pain is a common complaint, often associated with degenerative disc disease.
- Intraspinal masses typically raise concerns for neoplastic or infectious etiologies.
Observation:
- A 49-year-old male with a 20-year history of back pain presented with a 6-week history of left leg numbness and pain.
- Magnetic resonance imaging revealed a peripherally enhancing intraspinal mass at the L-3 level.
Findings:
- Histological examination of the completely removed mass revealed degenerated disc fragments encased in granulation tissue.
- The patient experienced complete symptom resolution following surgical excision.
Implications:
- Migrated disc fragments should be considered in the differential diagnosis of intraspinal masses, particularly in patients with a history of back pain.
- This case underscores the importance of considering non-neoplastic, disc-related pathology in the evaluation of intraspinal lesions.
