Abstract

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.
