RT Journal Article SR Electronic T1 E-cigarette or vaping product use-associated lung injury (EVALI) masquerading as COVID-19 JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e243885 DO 10.1136/bcr-2021-243885 VO 14 IS 7 A1 Ganne, Nandita A1 Palraj, Raj A1 Husted, Elizabeth A1 Shah, Ishan YR 2021 UL http://casereports.bmj.com/content/14/7/e243885.abstract AB SARS-CoV-2, the novel coronavirus causing COVID-19, has caused a global pandemic resulting in over 4 million deaths globally (data current as of 14 July 2021). E-cigarette or vaping product use-associated lung injury (EVALI) is a type of acute lung injury of unclear pathogenesis. The two pathologies present with overlapping clinical symptoms, laboratory values and imaging, making them difficult to distinguish, especially in the setting of a global COVID-19 pandemic. We present the case of a 32-year-old woman treated for COVID-19 despite multiple negative SARS CoV-2 PCR tests and nucleocapsid antibody test. On further investigation, she endorsed use of E-cigarettes and was subsequently diagnosed with EVALI. The patient was treated with oral and intravenous steroids, resulting in significant improvement in her symptoms. This case highlights the challenge of diagnosing rarer aetiologies of respiratory distress during the COVID-19 pandemic.
