Pre-operative CT scan shows air entrapment (black arrows) in the post epidural space at the C2 (A), T5 (B), and T7 (C) levels and in intervertebral foramina at the T5 (B), T7 (C), and T8 (D) levels.

Definitive findings of whole spine CT scan were multifocal air densities in the epidural space, intervertebral foramen, and paraspinal muscles between C1 and T9 and no obvious spinal cord compression (Fig. 1).
Post-operative CT scan shows nearly complete disappearance of air trapped (black arrows) in the epidural and intervertebral foramina at the C2 (A), T5 (B), T7 (C), and T8 (D) levels.
