Study Notes
Asbestos-Related Diseases
- Asbestos fibers inhaled cause lung and/or pleural diseases.
- Latency period is long (20-30 years) between exposure and disease development.
- Pleural disease is more common than lung disease, occurring in 50% of cases.
- A combination of pleural and lung disease is found in 40% of cases.
- Lung disease alone is present in 10% of cases.
Pleural Diseases
- Pleural plaques: Most common manifestation, appearing 20-30 years after asbestos exposure.
- Found on parietal pleura (underside of ribs), diaphragmatic pleura, and near the spine.
- Essentially diagnostic of asbestos exposure.
- Characteristic "holly-leaf" shaped opacities on chest X-rays (CXR).
- Distinct appearance on computed tomography (CT).
- Benign pleural effusion: A frequent early symptom.
