Pleural nodules may be single or multiple and vary in size, shape, and density.
| Terminology | explain |

| Pleural tuberculosis | Pleural nodules caused by Mycobacterium tuberculosis infection |
| pleural metastases | Malignant tumors from other sites metastasize to the pleura |
| Pleural mesothelioma | Malignant tumors originating in the pleura, related to asbestos exposure |
| pleural fibrosis | Fibrous tissue hyperplasia after chronic inflammation or injury of the pleura |
3. Diagnostic methods of pleural nodules
When pleural nodules are found, doctors usually recommend further testing to determine the cause. The following are common diagnostic methods:
| Check method | function |
|---|---|
| Chest CT | Provide clearer images to observe the size, shape and location of nodules |
| PET-CT | Assess the metabolic activity of nodules to help differentiate between benign and malignant |
| Pleural biopsy | Obtain tissue samples for pathological examination by puncture or thoracoscopy |
| Pleural effusion examination | Analyze the nature of effusion and assist in diagnosis |
4. Treatment options for pleural nodules
Treatment of pleural nodules depends on their cause. The following are common treatment options:
| Cause | treatment plan |

| infectious pleurisy | antibiotic treatment |
| Pleural tuberculosis | antituberculosis drug treatment |
| pleural metastases | Chemotherapy, targeted therapy, or immunotherapy |
| Pleural mesothelioma | Surgery, radiotherapy or combined treatment |
