Summary
Propriospinal myoclonus, a rare spinal condition, was successfully treated in a patient with cervical disc herniation. This case highlights a novel surgical approach for this previously unreported cause of myoclonus.
Area of Science:
- Neurology
- Neurosurgery
- Spinal Cord Disorders
Background:
- Propriospinal myoclonus is a rare spinal myoclonus with often unclear etiology.
- Secondary causes include trauma, tumors, and infections, but cervical disc herniation has not been previously reported.
Observation:
- A 53-year-old man presented with right C-6 radiculopathy and abdominal muscle myoclonus, exacerbated by movement.
- MRI revealed C-6 nerve root compression at C5-6 without cervical myelopathy.
- Electromyography confirmed propriospinal myoclonus.
Findings:
- This is the first reported case of propriospinal myoclonus caused by cervical disc herniation.
- Surgical discectomy and fusion successfully resolved the myoclonic movements.
Implications:
- Cervical disc herniation should be considered in the differential diagnosis of propriospinal myoclonus.
- Surgical intervention for cervical disc herniation can effectively treat associated propriospinal myoclonus.
- This study expands treatment options for spinal myoclonus disorders.
