| The cause of atelectasis is thought to be due to enlargement of silicotic lymph nodes based on image study. |
|
| The inhaled dust deposited in the bronchioles and alveoli reacts within the lung tissue to form silicotic nodules. |
|
| In a period of 18 months, we have encountered 4 cases of right middle lobe atelectasis associated with endobronchial silicotic lesions of right middle lobe bronchi. |
|
| Silicotic nodules were defined as discrete lesions with smooth, sharp borders and concentric laminated collagen fibers. |
|
| Any dust underground was undesirable, but tolerable limits of exposure to silicotic rock based on medical research were known. |
|
| Silicotic mediastinal lymphadenopathy can cause left vocal cord paralysis and dysphagia. |
|
| Silicosis was defined as the presence of palpable silicotic nodules on macroscopic examination of the lungs, which was then confirmed on microscopic examination. |
