    Abstract:
    We report 6 cases of spontaneous pneumomediastinum. It is defined not to have clear etiology such as trauma, and is comparatively rare disease developing suddenly. Our patients complained of chest or neck pain, dyspnea and pain when swallowing. They were 3 men and 3 women, who were young and did not have causal disease. Chest X-ray films and computed tomography (CT) scans revealed pneumomediastinum. All of them were treated conservatively and recovered completely within 10 days hospitalization. Spontaneous pneumomediastinum is uncommon and usually benign. Most patients require only conservative treatment. However, since it possibly develops tension pneumothorax, pneumothorax, or mediastinitis, careful observation is recommended never to overlook life-threatening condition. In addition, it is important to distinguish from Boerhaave syndrome, tracheal trauma and so on.
