Overview
- Physical examination of the chest in silicosis is often unremarkable, although a variety of abnormal breath sounds, including crackles, rhonchi, and/or wheezes, occur as the disease progress.
Physical Examination
- Physical examination of the chest is often unremarkable in simple silicosis, although a variety of abnormal breath sounds, including
- Fine crackles,
- Coarse crackles (often at end inspiration),
- Rhonchi, and/or
- Wheezes, have been reported to occur in approximately 25 percent of affected individuals [1].
- Patients with Progressive massive fibrosis frequently have
- Decreased breath sounds.
- Crackles are less common in PMF than in simple silicosis, but other adventitial sounds may be present.
- Look for other associated etiology if
- Digital clubbing
- Signs of chronic respiratory failure and
- cor pulmonale are present.
