case_images: (a) Axial CT lumbar spine demonstrated air in the spinal canal at L3 without compression of the thecal sac. (b) Sagittal CT lumbar demonstrated air in the spinal canal extending from the lumbar region to the lower thoracic spine at the upper limit of the scan.

case_images: CT abdomen and pelvis (later reconstructed into CT lumbar spine) demonstrated spontaneous pneumomediastinum and extramedullary PNR extending upward from L3 throughout the thoracic spine to the upper limit of the scan [Figure 1].
case_images: (a) Axial CT thoracic spine with air in the spinal canal communicating with the paravertebral extraforaminal space at the T4 level. (b) Sagittal CT thoracic demonstrates air in the spinal canal extending the entire length of the thoracic spine.

case_images: Subsequent CT thoracic spine [Figure 2] and CT cervical spine [Figure 3] showed the full length of the extradural air from C2-T12 and again at L3.
case_images: Axial and sagittal CT of the cervical spine demonstrating air in the dorsal spinal canal extending caudally to the C2 level.
