Nodules in pleura can be caused by pleurisy due to lung inflammation or tuberculosis, which leads to pleural thickening and confined bulging to form benign pleural nodules, or pleural nodules can be formed by proliferation and growth of primary pleural tumors and metastatic tumors in the pleura.
1. Pleurisy caused by lung inflammation or tuberculosis, resulting in fibrin exudation in the pleural cavity, fibrin deposition on the pleura leading to pleural adhesion and thickening, and the thickened pleura is confined to form benign pleural nodules.
2. Pleural mesothelioma, such as benign limited mesothelioma, diffuse malignant mesothelioma, pleural metastasis tumor, etc., can also present nodular proliferation and growth in the pleura.
Nodules in pleura can be caused by many reasons, so it is recommended that patients should go to the hospital as soon as possible to improve the relevant examination and receive treatment actively, so as to avoid delaying the condition.
