title: Pneumorrhachis.
abstract: The presence of air in spinal canal is called as "pneumorrhachis." Nontraumatic, noniatrogenic spontaneous spinal air is an uncommon case. Peripheral alveoli burst due to the increased pressure in alveoli in the case of trauma, asthma, pneumothorax, or pneumomediastinum. Air pass to the mediastinum and then to retropharyngeal space and reaches to epidural space. In this paper, a 44-year-old female patient who has a spontaneous pneumorrhachis in the epidural space in the spinal canal L5-S1 lumbar level has been presented.
