Spinal gas collection demonstrated at CT.
In 234 consecutive CT examinations of the lumbar spine, gas collection was observed in 4 cases with disk herniation, and in 6 cases of disk protrusion. In 3 cases free gas was found in the epidural space, and one patient presented an intraspinal gas-filled "bleb". Gas collection in intervertebral disk spaces and facet joints was found in a total of 60 patients. The CT findings and surgical results were compared to determine whether gas collection contributes to clinical symptoms. In most cases the presence of gas was not clinically important, but in one patient it presented as a spinal mass, causing pain and radiculopathy.
