A case of eosinophilic granulomatosis with polyangiitis associated with diffuse alveolar haemorrhage: A case report and case-based review.

A 76-year-old man with bronchial asthma was admitted for respiratory failure and bloody sputum. A significant drop in haemoglobin and multiple consolidations supported clinical diagnosis of diffuse alveolar haemorrhage (AH). Myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) was positive and urinalysis suggested glomerulonephritis.
