title: Idiopathic pulmonary hemosiderosis: favorable response to corticosteroids.
abstract: A 50-year-old Taiwanese woman had a history of massive hemoptysis occurring every 6 months for the past 4 years. After each bout of hemoptysis, chest roentgenography would show diffuse alveolar infiltration of bilateral lungs, which would usually resolve within 7 days. Transbronchial biopsy revealed diffuse alveolar hemorrhage and hemosiderin-laden macrophage infiltration. Idiopathic pulmonary hemosiderosis was diagnosed by excluding other glomerular, cardiac and immunological disorders. An initial dose of 20 mg prednisolone daily was tapered to 10 mg daily 1 month later. The patient is currently undergoing steroid therapy, and there have been no further episodes of hemoptysis.
