Conclusion:
Pneumorrachis caused by degenerative disc disease is a rare condition that can rarely lead to a radicular syndrome. Its prevalence increases with age and it may be due to two mechanisms: a gas-containing disc herniation or an intraspinal free gas. CT scan is the preferred imaging technique. The treatment is conservative at first. CT guided needle aspiration can be suggested despite the risk of relapse. Surgery remains the treatment of choice in case of neurological signs or recurrence under conservative treatment.
