A 43-Year-Old Brazilian Man with Acute Impairment of Lung Function and Pulmonary Nodules with Features of Electronic Cigarette or Vaping Product Use-Associated Lung Injury (EVALI)

Patient: gender, XX-year-old Final Diagnosis: e-cigarette or vaping product use-associated lung injury Symptoms: Chest pain • chills • cough • diarrhea • fever • progressive dyspnea • wheezing Clinical Procedure: Bronchoalveolar lavage • bronchoscopy • chest CT scan • chest xray • lung biopsy • mechanical ventilation • SARS-CoV-2 RT-PCR • serology Specialty: Pulmonology • Radiology OBJECTIVE: Unusual clinical course BACKGROUND: Electronic smoking devices were created, and their production industrialized, recently. Since their creation, their use has spread widely. This increase in users led to the appearance of a new lung condition. In 2019, the CDC established the criteria for the diagnosis of electronic cigarette or vaping product use-associated lung injury (EVALI) and the eponym EVALI is now widely recognized. The condition results from the inhalation of heated vapor, which damages the large and small airways and alveoli. CASE REPORT: This report presents the case of a 43-year-old Brazilian man with acute impairment of lung function, pulmonary nodules on chest computed tomography (CT) and features of EVALI. He was hospitalized after 9 days of respiratory symptoms due to worsening dyspnea, and underwent a bronchoscopy on the same day. His condition evolved into severe hypercapnic respiratory failure that took 3 weeks to improve, and he underwent a surgical lung biopsy that showed an organizing pneumonia pattern. He was discharged after 50 days of hospitalization. Infectious diseases and other lung conditions were ruled out on clinical, laboratory, radiological, epidemiological, and histopathological grounds. CONCLUSIONS: In conclusion, we report the unusual presentation of EVALI on chest CT showing nodules instead of a ground-glass pattern, as stated in the CDC definitions of a confirmed case. We also report the progression to a critical clinical state and, after treatment, the evolution to complete recovery. We also draw attention to the difficulties in diagnosing and managing the disease, especially at a time when COVID-19 has emerged.
