A 62-year-old man presented with worsening dyspnoea, haemoptysis and reduced exercise tolerance. He was found to be hypoxaemic with bilateral basal opacification on chest imaging, but inflammatory markers, respiratory virus PCR and sputum culture demonstrated no signs of infection. The patient reported having initially mild, yet progressive, symptoms since he started vaping 14 months previously. He was treated with oxygen therapy, supportive care and cessation of vaping. Chest imaging at discharge showed marked improvement of previous bilateral opacification and the patient returned to baseline exercise tolerance, with no oxygen requirement. Vaping is becoming more common in the UK and this case demonstrates the importance of considering electronic vaping-associated lung injury in cases of non-infective lung injury.
一名62岁男性出现呼吸困难、咯血加重及运动耐量下降。胸部影像学检查发现他存在低氧血症且双侧肺底部有混浊影，但炎症指标、呼吸道病毒聚合酶链反应（PCR）及痰培养均未显示感染迹象。患者自述自14个月前开始吸电子烟以来，最初症状轻微，但呈进行性加重。他接受了氧疗、支持治疗并停止吸电子烟。出院时的胸部影像学检查显示先前双侧混浊影明显改善，患者恢复至基线运动耐量，无需吸氧。吸电子烟在英国正变得越来越普遍，该病例表明在非感染性肺损伤病例中考虑与电子烟相关的肺损伤的重要性。
