Spontaneous pneumomediastinum, or Hamman's syndrome, is a rare condition which may present with the symptoms of chest pain, dyspnoea, dysphagia, or neck pain. The signs of subcutaneous emphysema and Hamman's crunch (the presence of a crepitance sound that varies with the heartbeat on auscultation of the precordium) are usually present. A case of this syndrome occurring in an elderly patient with none of the recognised risk factors is presented.
自发性纵隔气肿，即哈曼综合征，是一种罕见疾病，可能表现为胸痛、呼吸困难、吞咽困难或颈部疼痛等症状。通常会出现皮下气肿体征和哈曼捻发音（在心前区听诊时出现随心跳变化的捻发音）。本文报告了一例发生在无任何已知危险因素的老年患者身上的该综合征病例。
