E-cigarette use related lung disease, review of clinical and imaging findings in 3 cases

Electronic-cigarette use (vaping), has gained popularity among the young adult population, causing an alarming rise in electronic-cigarette, or vaping, product use-associated lung injury (EVALI). The specific chemical agent(s) responsible for lung injuries remains to be further investigated, but tetrahydrocannabinol, the active ingredient in marijuana, and vitamin E acetate are involved in most cases. A variety of pulmonary diseases causing different imaging findings have been described with EVALI. The clinical and imaging findings of three cases recently seen in our emergency department are reviewed.
