Spontaneous pneumomediastinum is a rare disease process with no clear etiology, although it is thought to be related to changes in intrathoracic pressure causing chest pain and dyspnea. We present a case of a 17-year-old male with acute chest pain evaluated initially by bedside ultrasound, which showed normal lung sliding but poor visualization of the parasternal and apical cardiac views due to significant air artifact, representing air in the thoracic cavity. The diagnosis was later verified by chest radiograph. We present a case report on ultrasound-diagnosed pneumomediastinum, and we review the diagnostic modalities to date.
自发性纵隔气肿是一种病因不明的罕见疾病过程，尽管人们认为它与胸腔内压力变化有关，可导致胸痛和呼吸困难。我们报告一例17岁男性急性胸痛病例，最初通过床边超声进行评估，超声显示肺滑动正常，但由于明显的气体伪像，胸骨旁和心尖部心脏视图显示不佳，提示胸腔内有气体。该诊断后来通过胸部X线片得到证实。我们报告一例超声诊断纵隔气肿的病例，并回顾了迄今为止的诊断方法。
