Radiologic Review With Pathology Correlation of E-Cigarette or Vaping Product Use-associated Lung Injury

More than 2000 cases of vaping-associated lung injury have been reported in a recent outbreak, including >40 deaths. Although chest imaging is integral in the evaluation of these patients and is often abnormal, the spectrum of findings and the role of imaging in the diagnosis are not widely appreciated. The aim of this review is to highlight the imaging findings of vaping-associated lung injury. Basilar-predominant ground-glass opacities and/or consolidations, often with areas of subpleural or lobular sparing, are the most common pattern, and many other patterns are known to occur. Radiologists are encouraged to become familiar with the different imaging patterns of vaping-associated lung injury. The diagnosis should be considered in patients who have vaped within 90 days of onset of symptoms and present with bilateral lung opacities.
