E-cigarette/vaping-associated lung injury (EVALI) has been recently reported in the radiology literature and has become an urgent public health matter as stated by the Center for Disease Control and Prevention. As of October 22, 2019, there have been 1,604 cases in the United States territory with 34 confirmed deaths. Patients <20 years represent 36% of EVALI cases. Moreover, the use of vaping among adolescents and teenagers has progressively increased in recent years. Although the exact cause and mechanism of injury remain a subject of investigation, clinical suspicion along with imaging findings and in some cases, bronchoscopic results, remain the mainstay in the diagnosis of EVALI, after excluding infection. Reported imaging patterns of EVALI include hypersensitivity pneumonitis, diffuse alveolar hemorrhage, acute eosinophilic pneumonia, diffuse alveolar damage, lipoid pneumonia, and giant cell interstitial pneumonia. We describe computed tomography (CT) findings of EVALI patients from our institution Read More

The incidence of e-cigarette, or vaping, product use associated lung injury (EVALI) has been increasing since the summer of 2019. At least seven distinct patterns of lung injury have been described with this emerging disease (1). A recent report from the United States Centers for Disease Control and Prevention indicates that approximately 15% of patients diagnosed with EVALI have been in the pediatric age group (2). Because of the potential legal and social repercussions of vaping and cannabis use, pediatric patients may be disinclined to admit to use of electronic cigarettes. As such, recognition of the potential imaging patterns of this disease may allow the pediatric radiologist to raise the possibility of EVALI to facilitate timely diagnosis and appropriate management of the disease.

This educational exhibit will review the imaging findings seen in the various patterns of lung injury identified with this increasingly common lung disease. We will also discuss the indications for obtaining imaging studies in patients with suspected EVALI. In addition, we will describe the potential clinical presentations in these patients.
