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.
