title: [A case of pneumomediastinum caused by closed tracheal injury during the game of Kendo (Japanese fencing)].
abstract: A patient was injured accidentally on his neck during the game of Kendo (Japanese fencing). After his neck injury, he continued to play Kendo because there was no symptom at that time. Starting 10 minutes after the injury, swelling as well as pain on the neck and dyspnea developed gradually. After the admission to the emergency room, computed tomography revealed pneumomediastinum. Nasal endotracheal intubation was performed gently under fiberscopy. Dyspnea and pneumomediastinum improved gradually during the 6 days after the admission. A patient who has received a closed injury on his neck without immediate symptoms or signs must be observed closely because the absence of symptoms or signs does not guarantee the absence of the injury of the trachea.
