Vaping and diffuse alveolar hemorrhage: All EVALI is not created equal

Abstract

E-cigarette, or vaping product, use associated lung injury (EVALI) refers to respiratory illness in patients with recent vaping and no signs of infection or underlying illness. EVALI can cause severe acute respiratory distress syndrome and death. A spectrum of diagnoses can fit the description of EVALI since it relies heavily on nonspecific, radiographic findings. We present a rare case of EVALI in which a patient with a history of vaping presented with acute hypoxemia and was diagnosed with diffuse alveolar hemorrhage (DAH). The mechanism of injury of DAH due to vaping is unknown, and further research into the topic is required.

Keywords: E-cigarette; bronchoscopy; hypoxemia.
