Spinal Vacuum Phenomenon

Abstract
Spinal vacuum phenomenon may be encountered in many circumstances, such as degeneration of the intervertebral disk, disk injury, vertebral metastases, ischemic vertebral collapse, Schmorl''s nodes and infectious processes. The high spatial and densitometric resolution of computed tomography (CT) makes it possible to show gas in tissues with higher frequency than by conventional radiography. In certain circumstances, the CT findings may be the decisive diagnostic element.
