“…First described by Magnusson in 1937, intervertebral discs develop fissures in the nucleus pulposus as they degenerate in old age (10). These fissures passively absorb gas from surrounding tissues (7,11). The gas is found to be composed mostly of nitrogen (12).…”

Out of 620 consecutive examinations of the atlanto-odontoid joint in patients referred for computed tomography (CT) of the brain or paranasal sinuses, gas collection within the atlanto-odontoid joint was observed in 12 (1.9%). Degenerative abnormalities at the atlanto-odontoid joint were significantly more frequent in patients with a gas-induced vacuum phenomenon than in an age-matched control group. The CT findings and association of the vacuum phenomenon with osteoarthritis of the atlanto-odontoid joint are discussed.

“…Although gas is often observed in degenerated intervertebra1 disks (6,8,(11)(12)(13)(14)(16)(17)(18), the presence of gas in the spinal canal is reported to be a rare finding. In a series of 2 500 CT scans spinal gas was observed in only 7 cases (17).…”
