A case report describing EVALI (e-cigarette or vaping product use-associated lung injury) presenting as diffuse alveolar hemorrhage (DAH) in an adolescent patient, examining clinical features, workup, and management.
EVALI manifested as DAH in an adolescent, an uncommon and severe presentation; the case highlights the diagnostic and therapeutic challenges when vaping-related lung injury mimics other causes of pulmonary hemorrhage.
Single case report limits generalizability; causality between vaping and DAH cannot be firmly established without broader evidence; detailed treatment outcomes and follow-up duration are not fully characterizable from the abstract alone.
Clinicians should consider EVALI as a cause of diffuse alveolar hemorrhage in adolescents with a vaping history, even when the presentation is atypical. A thorough vaping/e-cigarette use history is essential in any adolescent with unexplained pulmonary hemorrhage.
