title: Diffuse pulmonary hemorrhage and rapidly progressive renal failure. An uncommon presentation of Wegener's granulomatosis.
abstract: A 57 year old woman presented with rapidly progressive renal failure and diffuse pulmonary hemorrhage and life-threatening respiratory failure promptly developed; these conditions resolved after bilateral nephrectomy. Renal pathology revealed rapidly progressive glomerulonephritis and vasculitis with granular deposition of immunoglobulin on immunofluorescent staining. One year later, multiple nodular cavitating pulmonary infilrates developed, and lung biopsy was diagnostic of Wegener's granulomatosis. Therapy with cyclophosphamide resulted in resolution of the pulmonary lesions. Diffuse pulmonary hemorrhage and rapidly developing renal failure mimicking Goodpasture's syndrome was the initial manifestation of Wegener's granulomatosis in this patient.
