Morphologic Characteristics and Clinical Significance of Computed Tomography and Magnetic Resonance Imaging Findings of Spinal Epidural Gas

To evaluate the morphologic characteristics and clinical significance of epidural gas based on computed tomography (CT) and magnetic resonance imaging (MRI) findings and to determine their relationship with radiculopathy. Between March 2009 and November 2018, 110 epidural gas lesions were identified in 103 patients who underwent both CT and MRI for suspected herniated disc in the authors' institution.
