CTICasesAcute eosinophilic pneumonia
Imaging findings
Chest radiograph and CT show bilateral, symmetric lobular ground-glass opacities, septal thickening, and lower-lobe-predominant consolidations in a patient presenting with acute dyspnea, hypoxemia, and peripheral eosinophilia (40%) after vaping CBD oil. The findings resolved rapidly within 24 hours of corticosteroid therapy.
Key takeaways
Acute eosinophilic pneumonia is a rare, severe lung injury that can be triggered by new or altered inhalational exposures, including vaping of CBD oils. It typically presents with acute respiratory distress, diffuse ground-glass opacities, and marked eosinophilia, and is highly responsive to steroids.
