A case of cocaine-induced eosinophilic pneumonia: Case report and review of the literature.

Cocaine is a commonly abused recreational drug in the United States. An adult man developed non-specific pleuritic chest pain, pharyngitis and odynophagia after inhaling cocaine. Initial laboratory results revealed eosinophilia. Bronchoalveolar lavage also showed eosinophilia in the lavage fluid. These findings suggested the diagnosis of eosinophilic pneumonia. Chest imaging revealed scattered bilateral opacities and interstitial infiltrates. After initiation of systemic corticosteroids, the patient reported symptomatic resolution and radiographic clearance was achieved at 2 months follow up.
