The presence of air in the vertebral canal (extracranial epidural emphysema) has been described in veterinary medicine in isolated case reports mainly associated with intervertebral disc disease. This case of a nine-year-old male neutered greyhound describes a different aetiology where the presence of extensive epidural emphysema was associated with pneumomediastinum, pneumothorax and subcutaneous emphysema following thoracotomy for a lung lobectomy. The extracranial epidural emphysema was managed conservatively by sealing of the thoracotomy site and treating the pneumothorax. Extracranial epidural emphysema should be considered as a possible complication of thoracic surgery if extensive subcutaneous emphysema and/or pneumomediastinum develops.
