Lumbar spine vacuum disc phenomenon

    • Vertebral Pneumatocysts

      pneumatocyts were associated with the vacuum phenomenon in an adjacent disc or facet joint. Only 1 case did not have any demonstrable vac-uum phenomenon. However, this patient had a limited examination (only the last 3 lumbar inter-vertebral discs); therefore we could not exactly rule out the presence of the vacuum phenomenon in other regions.

Its prevalence on conventional radiographs ranges from 2% in healthy adults to 21% in asymptomatic elderly people.22 Although IVP can occur with spinal in-

    • Air in the L4-5 Epidural Space Appearing as Disc Herniation

      sequent spine CT, however, revealed air in the L4-L5 disc space consistent with vacuum disc phenomenon which was chronic and appeared on abdominal ct scans done several years prior (Figure 2). DISCUSSION. Gas production or “vacuum phenomenon” in the intervertebral space may be a byproduct of disc degeneration.

The detection of gas within a vertebral disk, espe-cially in the lumbar region, is often consistent with the vacuum phenomenon (8–11). This finding represents an accumulation of gas between the vertebral bodies that is typically more than 90% nitrogen (12). In the
