Although spinal gas is common and can be found in various sites and lesions, it should prompt a search for the underlying cause, given that the clinical significance of ectopic gas varies from benign to scary. Spinal gas can occur in the traumatic, iatrogenic, degenerative, osteoporotic, infectious, or neoplastic lesions. The imaging similarity may cause the misdiagnosis or delayed diagnosis which sometimes requires immediate attention. The pattern of gas distribution, detailed appearance, clinical history, and findings on examination can provide clues to diagnosis. Computed tomography is the best method for sensitive detection of gas.
