Intervertebral disc vacuum phenomena

Vacuum phenomena involving the intervertebral discs is usually a result of accumulation of gas (principally nitrogen) within the crevices of the intervertebral discs or adjacent vertebrae.

It is a relatively common occurrence which can be observed in 1-3% of spinal radiographs and may even reach a prevalence of 20% in elderly individuals 5.

This commonly occurs in association with intervertebral disc degenerative disease.

However, the presence of gas does not categorically imply merely degenerative disc disease, as other processes can lead to discs containing gas. Examples of other conditions with gas includes:

There are occasional reports of nerve root compression associated with herniated intradiscal gas 6: pneumatic nerve root compression

It was first described by Magnusson in 1937 5.
