Imaging findings
Chest radiography shows profound, bilateral, symmetric airspace opacities predominantly affecting the middle and lower lung zones. High-resolution CT shows diffuse ground-glass opacities and areas of consolidation, characteristic of diffuse alveolar hemorrhage, with rapid clearance and nearly complete normalization of the lungs on follow-up radiographs a few weeks after therapy.
Key takeaways
Goodpasture syndrome is an autoimmune condition caused by anti-glomerular basement membrane antibodies that can manifest as life-threatening diffuse alveolar hemorrhage. While renal failure is common, a minority of patients present with isolated pulmonary hemorrhage and normal renal function. The disease responds rapidly to corticosteroid therapy, showing dramatic radiographic improvement.
