Pulmonary hemorrhage, also lung hemorrhage, is a potentially serious conditions with a large number of possible underlying causes.
General
- Many causes.
A few causes:
- Trauma.
- Acute bronchopneumonia.
- Lung cancer, e.g. lung adenocarcinoma.
- Pulmonary hypertension.
- Infection, e.g. tuberculosis.
- Bronchiectasis.
Pulmonary hemorrhage syndromes:[1]
- Goodpasture syndrome.
- Idiopathic pulmonary hemosiderosis.
- Vasculitis-associated hemorrhage (hypersensitivity angiitis, Wegener's granulomatosis).
- Systemic lupus erythematosus.
Radiology
- Airspace opacity.
Microscopic
Features:
- Red blood cells in the airspaces - abundant.
- +/-Siderophages (hemosiderin-laden macrophages).
- Can count (distinct) granules (unlike in smoker's macrophages).
DDx:
- Decomposition.
