2024年6月5日 · Silicosis (plural: silicoses) is a fibrotic pneumoconiosis caused by the inhalation of fine particles of crystalline silicon dioxide (silica). Certain occupations such as mining, quarrying, denim sandblasting 9 and tunneling are associated with silicosis.

Silicosis is a type of pneumoconiosis where silicon dioxide is deposited in the airways, causing directly toxic effects on the lung parenchyma and also activating macrophages and the inflammatory cascades which is thought to exacerbate the damage.

Aids to differentiating cause: silicosis vs sarcoidosis vs tuberculosis. calcified lymph nodes in tuberculosis tend to affect the mediastinum asymmetrically and unilaterally; diffuse bilateral lymph node involvement is more common in sarcoidosis; silicosis: the patient usually has a history of a silica-exposure related job (as in this case)

Nodularity often accompanies the fibrosis. Many types of coal have silica components, which results in the more specific term of silicosis. Calcified mediastinal lymph nodes may also be a feature.

Patient has an occupational history of sandblasting. He has a known history of fibrotic pneumoconiosis secondary to silicosis, but presented with acute findings of congestive heart failure and pulmonary alveolar edema as visualized on the CT.

2022年8月25日 · Silicosis (plural: silicoses) is a fibrotic pneumoconiosis caused by the inhalation of fine particles of crystalline silicon dioxide (silica). Certain occupations such as mining, quarrying, denim sandblasting 9 and tunneling are associated with silicosis.

The findings of innumerable micronodules with predominant upper lobe affection, associated with the provided history of occupational exposures make simple silicosis the most probable diagnosis, though coal workers' pneumoconiosis and talcosis could give very similar radiological findings.

These two entities have similar radiological appearances, although they have different histological findings. However, the presence of a subpleural distribution of some nodules, the "egg-shell" lymph node calcification and the exposure to sand-working are highly suggestive of silicosis.

2024年6月11日 · Along with silicosis, asbestosis, berylliosis, and talcosis, CWP is a fibrotic pneumoconiosis. Radiographic features. Despite histologic differences between silicosis and CWP, the two entities are not easily distinguished from one another on imaging studies. Simple CWP Plain radiograph

2024年6月11日 · These classically develop in the context of certain pneumoconioses (especially coal worker's pneumoconiosis and silicosis) although similar mass-like densities have occasionally been described with talcosis. Radiographic features Plain radiograph. May be seen as large symmetric bilateral opacities with irregular margins in the upper lobes 3. CT
