目的：探讨纵隔积气的病因及影像学表现。方法回顾性分析33例纵隔积气的病因及影像学表现。结果纵隔积气包括自发性积气和外伤性积气。自发性纵隔积气12例，原发疾病包括支气管哮喘2例，肺气肿2例，肺结核2例，肺间质性疾病1例，胆汁反流性胃炎1例，严重呕吐1例，剧烈咳嗽3例。外伤性纵隔积气21例，包括外伤性 Macklin 效应18例，外伤性气管破裂2例，食管破裂1例。纵隔积气常伴有肺间质积气、皮下积气、腹腔后积气。结论纵隔积气的病因多样化，影像学检查对探其病因有一定作用。

Objective To evaluate imaging findings and causes of pneumomediastinum.Methods Imaging findings of pneumome-diastinum in 33 cases were analyzed retrospectively.Results Pneumomediastinum may secondary to spontaneous(n=12)or trauma (n=21).Etiology of spontaneous pneumomediastinum included asthma(n=2),pulmonary emphysema(n=2),pulmonary tuberculo-sis(n=2),pulmonary interstitial disease(n= 1 ),bile reflux gastritis(n= 1 ),severe vomiting(n= 1 )and cough(n= 3 ).Traumatic pneumomediastinum included traumatic Macklin effect(n= 18),traumatic tracheobronchial disruption(n=2),and oesophageal rup-ture(n=1 ).Pneumomediastinum was accompanied by pulmonary interstitial emphysema and subcutaneous emphysema or retro-pneumoperitoneum.Conclusion Etiologies of pneumomediastinum are varied.Thoracic DR and CT may help in detection of etiology of pneumomediastinum.
