[Massive alveolar haemorrhage in Wegener's granulomatosis]

Wegener's granulomatosis is a systemic vasculitis with involvement of primary granulomatous upper and lower respiratory tract, glomerulonephritis and vasculitis of small vessels. The lung disease ranges from asymptomatic pulmonary nodules to pulmonary infiltrates and fulminant alveolar haemorrhage. The prognosis is poor due to kidney and respiratory failure, although the data are changing due to new treatments with glucocorticoids and cyclophosphamide. We report a case with severe lung disease, which after appropriate anamnesis, multiple tests, and optimal sequential action, the patient was diagnosed with Wegener's granulomatosis. This disease has a low incidence in the Emergency Department, where the patient history supported by the appropriate additional provides a diagnostic suspicion. It is important that the Emergency Department has the skills to manage the stability in these patients in order to resolve their symptoms.
