Diffuse Alveolar Hemorrhage - PMC
Diffuse alveolar hemorrhage (DAH) is a life-threatening and medical emergency that can be caused by numerous disorders and presents with hemoptysis, anemia, and diffuse alveolar infiltrates. Early bronchoscopy with bronchoalveolar lavage is usually required to confirm the diagnosis and rule out infection.
Radiological aspects of diffuse alveolar haemorrhage
DAH is radiologically characterised by a nonspecific alveolar-filling pattern. Diagnosis or suspicion of DAH needs to be supported by the evidence of haemoptysis and/or rapid-onset anaemia. CT is superior in detecting ground-glass opacities and is required in cases of suspected DAH with normal CXR f …
