Traumatic pneumorrhachis (PR) is a rare entity, consisting of air within the spinal canal. It can be classified as epidural or subarachnoid, identifying the anatomical space where the air is located, and is associated with different etiologies, pathology, and treatments. ⋯ Traumatic PR is an asymptomatic rare clinical entity and often is underdiagnosed. It usually resolves by itself without specific treatment. We stress the significance of this information to trauma specialists, so that they may better differentiate between epidural and subarachnoid PR. This is of great significance because subarachnoid PR is a marker of severe injury. The management of traumatic PR has to be individualized and frequently requires multidisciplinary treatment, involving head, chest, and/or abdomen intervention.
