Abstract
A patient developed fever, bronchoconstriction, hypoxaemia, pulmonary infiltrates, and serum and bronchoalveolar lavage fluid eosinophilia on two occasions after inhaling crack cocaine. Transbronchial biopsy specimens showed normal lung parenchyma but a dense eosinophilic infiltrate within the bronchial wall. Both episodes resolved promptly after treatment with corticosteroids. Eosinophilic lung disease may be a steroid responsive complication of crack cocaine abuse.
