Introduction:
Pneumorrachis is a rare phenomenon defined as the presence of intraspinal air. It can be caused by various etiologies, mainly trauma and medical procedures such as spine surgery or epidural anesthesia. Less common causes of pneumorrachis include spinal infection, tumoral, or degenerative disc diseases. It is usually an asymptomatic and incidental imaging finding. However, it can seldom lead to radicular or spinal nerve compression [1].
We report herein two cases of spontaneous pneumorrachis due to degenerative disc disease and discuss the mechanism, diagnosis, and management of this rare condition.
