Lung Injuries from Vaping Have Characteristic Patterns on CT (IMAGE)
Caption
Images in a 39-year-old man with respiratory failure hospitalized for 10 days with an electronic cigarette or vaping product use-associated lung injury manifesting as an acute lung injury pattern at CT with some CT features suggesting a hypersensitivity pattern. (a, b) Axial enhanced CT images through the (a) mid and (b) lower lungs at presentation show multifocal areas of ground-glass opacity with prominent lobular low attenuation in the bases (arrows) suggesting small airway obstruction in addition to the ground-glass opacity. (c, d) Axial unenhanced CT images through the (c) mid and (d) lower lungs obtained 64 days after presentation show complete clearing of lung parenchymal abnormalities. Right middle lobe opacity (c) reflects site of surgical lung biopsy, which showed acute lung injury with organization, but no granulomas or other features typical of hypersensitivity pneumonitis.
