CTICasesLupus-associated diffuse alveolar hemorrhage
Imaging findings
CT scan of an SLE patient shows patchy, nodular ground-glass opacities and areas of consolidation. Bronchoscopy confirmed diffuse alveolar hemorrhage (DAH) showing fresh blood and hemosiderin-laden macrophages.
Key takeaways
Diffuse alveolar hemorrhage is a rare, life-threatening manifestation of SLE. It is caused by pulmonary capillaritis or vasculitis and typically presents with patchy or diffuse ground-glass opacities, drop in hematocrit, and hypoxia, even in the absence of hemoptysis.
