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.
