Correct answer: C — Acute eosinophilic pneumonia

Acute eosinophilic pneumonia can follow a recent change in smoking exposure and presents with febrile hypoxaemic respiratory failure, diffuse infiltrates and BAL eosinophilia. Peripheral eosinophilia is often absent initially. It usually responds rapidly to systemic corticosteroids after infection is excluded.
