A 23-year-old man presented to the emergency department with severe, central, pleuritic chest pain. The pain was present on waking and exacerbated by movement. On examination, supraclavicular and anterior chest wall surgical emphysema was noted, otherwise examination and initial observations were normal. A chest x-ray and subsequent chest CT demonstrated a pneumomediastium with significant subcutaneous emphysema. There was no history of vomiting or chest trauma, but the patient had inhaled mephedrone, a synthetic stimulant drug, 36 h prior. Pneumomediastinum is an uncommon complication of inhalational drug use.
一名23岁男性因严重的中央性胸膜炎性胸痛就诊于急诊科。疼痛在醒来时出现，并因活动而加重。检查时，发现锁骨上及前胸壁皮下气肿，其他检查及初始观察均正常。胸部X线及随后的胸部CT显示纵隔气肿伴明显皮下气肿。患者无呕吐或胸部外伤史，但在36小时前吸入了合成兴奋剂药物甲氧麻黄酮。纵隔气肿是吸入性药物使用的一种罕见并发症。
