Summary
Early sarcoidosis can cause bronchial narrowing, even without lung fibrosis. Consider this possibility in patients with breathlessness or wheezing, and use bronchography alongside bronchoscopy for diagnosis.
Area of Science:
- Pulmonary Medicine
- Respiratory Diseases
Background:
- Sarcoidosis is a multisystem inflammatory disease.
- Early stages may present with respiratory symptoms.
Observation:
- Four patients with early sarcoidosis developed bronchial narrowing or occlusion.
- Chest X-rays showed no signs of pulmonary fibrosis.
- Patients experienced breathlessness and wheezing with obstructive ventilation defects.
Findings:
- Bronchography revealed bronchial stenoses not visible during bronchoscopy.
- Bronchial narrowing is a potential early manifestation of sarcoidosis.
Implications:
- Bronchial narrowing should be considered in sarcoidosis patients with respiratory symptoms.
- Bronchography is a valuable tool to supplement bronchoscopy for diagnosing bronchial narrowing in sarcoidosis.
