Imaging findings
CT imaging of a young female patient shows acute, diffuse consolidations and extensive ground-glass opacities throughout both lungs. A follow-up scan obtained several days later shows rapid clearance and resolution of the opacities.
Key takeaways
Diffuse alveolar hemorrhage (DAH) is a life-threatening pulmonary complication that can occur in patients with systemic lupus erythematosus (SLE), often as the presenting manifestation of a lupus flare. DAH typically presents on imaging as bilateral, symmetric, or patchily distributed ground-glass opacities and consolidations that characteristically clear rapidly within a few days once bleeding stops or immunosuppressive treatment is initiated.
