CTICasesEVALI mimicking radiation pneumonitis in a melanoma patient
Imaging findings
Surveillance CT scan in a 40-year-old female treated for melanoma shows new, curvilinear ground-glass opacities in the lower lobes with subpleural sparing. Further history revealed recent use of a THC-concentrate vaping pen, confirming EVALI.
Key takeaways
Surveillance imaging in oncologic patients can incidentally detect EVALI. The subpleural-sparing ground-glass pattern should raise suspicion for vaping-associated injury, requiring active clinical questioning.
