== Etiologies ==

* Pathologic capillaritis (most common), caused by pulmonary inflammation
** Primary small-vessel vasculitis: [[GPA]], [[EGPA]], [[MPA]], isolated pauci-immune pulmonary capillaritis, idiopathic pauci-immune glomerulonephritis
** Primary immune complex-mediated vasculitis: [[Goodpasture syndrome]], [[Henoch-Schönlein purpura]]
** Secondary vasculitis: [[SLE]], [[RA]], [[antiphospholipid antibody syndrome]], [[mixed connective tissue disease]], [[polymyositis]], [[dermatomyositis]]
** Essential cryoglobulinemia
** [[Behcet disease]]
** Acute lung transplantation rejection
** Autologous bone marrow transplantation
** Drug-induced, including chemotherapy, [[propylthiouracil]]
* No pathologic capillaritis (i.e. bland pulmonary hemorrhage, RBC leak without damage to the capillaries)
** Idiopathic pulmonary hemosiderosis
** Coagulopathy, including anticoagulants, antiplatelets, thrombolytics, [[DIC]]
** Mitral stenosis and pulmonary veno-occlusive disease
** Inhalational injury, including isocyanates, crack cocaine, retinoic acid
** [[Goodpasture syndrome]]
** [[SLE]]
** Drug-induced, including [[amiodarone]], [[penicillamine]], [[nitrofurantoin]]
* Diffuse alveolar damage
** Bone marrow transplantation
** Inhalation
** Cytotoxic drug therapy
** Radiation therapy
** [[ARDS]]
** Infection
** Malignancy
** Embolism

=== Infections ===

* Immunocompromised: [[CMV]], [[adenovirus]], [[invasive aspergillosis]], [[Mycoplasma]], [[Legionella]], [[Strongyloides]]
* Immunocompetent: [[Influenza|influenza A]], [[dengue]], [[leptospirosis]], [[malaria]], [[Staphylococcus aureus]] pneumonia
** Also: [[CMV]], [[hantavirus]] pulmonary syndrome
