The presentation may vary from mild, chronic respiratory symptoms to an acute, catastrophic, life-threatening pulmonary hemorrhage. When symptoms are indolent, diagnosis may be delayed by months or years. Early, aggressive treatment is imperative in cases of pulmonary vasculitis. Cumulative lung damage due to ongoing inflammation can lead to pulmonary fibrosis.
