The detection of a vacuum phenomenon within the intervertebral disk usually confirms the diagnosis of degenerative disease rather than an infective process. A similar phenomenon in the vertebral body generally indicates ischemic necrosis. However, spinal infection may rarely be accompanied by intradiscal or intraosseous gas so that the latter finding does not entirely exclude the possibility of infection. Three cases are reported to illustrate gas formation in association with vertebral infection.
椎间盘内真空现象的检测通常可确诊退行性疾病，而非感染性病变。椎体出现类似现象通常提示缺血性坏死。然而，脊柱感染很少会伴有椎间盘内或骨内气体，因此后一种表现并不能完全排除感染的可能性。本文报告3例病例，以说明与椎体感染相关的气体形成情况。
