Spontaneous pneumomediastinum (SPM) is an uncommon, self-limiting condition resulting from alveolar rupture in young adults. There are asthma, illicit drug use, and activities triggering a Valsalva maneuver as causes of developing SPM. We report two patients who were diagnosed with SPM in the absence of known predisposing factors and without any clinical sign of subcutaneous emphysema of the neck, the most common physical finding on presentation. Both of them developed dysphagia after swallowing a peach seed and boned rib of pork, respectively. SPM was suspected after performing lateral neck X-ray, and the diagnosis of SPM was confirmed by chest CT. These cases showed the importance of performing the lateral neck X-ray to screen SPM in patients with dysphagia.
自发性纵隔气肿（SPM）是一种不常见的自限性疾病，由年轻成年人的肺泡破裂引起。哮喘、非法药物使用以及引发瓦尔萨尔瓦动作的活动是导致SPM的原因。我们报告了两名患者，他们在没有已知诱发因素且没有颈部皮下气肿这一最常见体征的任何临床迹象的情况下被诊断为SPM。他们分别在吞咽了桃核和猪排骨后出现吞咽困难。在进行颈部侧位X线检查后怀疑为SPM，胸部CT证实了SPM的诊断。这些病例表明了对吞咽困难患者进行颈部侧位X线检查以筛查SPM的重要性。
