- Cardiac.
- Subacute infective endocarditis.
- Cyanotic heart disease.
- Atrial myxoma.
- Lung:
- Lung abscess.
- Empyema.
- Cystic fibrosis.
- Idiopathic pulmonary fibrosis.
- Tuberculosis.
- Bronchiectasis.

- Bronchogenic carcinoma (most commonly small cell).
- Idiopathic.
- Not COPD.
- Gastrointestinal:
