On radiological studies, pleural plaques are visualized using conventional chest x-rays and computed tomography scans (CT scans). The locations of the lesions are mostly in the parietal pleura of the lungs, especially in the posterior/lateral regions of the thorax, diaphragmatic domes, and lung fissures.
The portion of the pleura seen as the outer layer covers the chest wall, the diaphragm and the mediastinum and is often also misleadingly called the parietal pleura. A correct anatomical nomenclature refrains from using the ambiguous terms visceral and parietal in favour of a 4-portion system based on the structures the pleura covers: pulmonary ...
Chemicals such as bleomycin, tetracycline (e.g., minocycline), [2] povidone-iodine, or a slurry of talc can be introduced into the pleural space through a chest drain. The instilled chemicals cause irritation between the parietal and the visceral layers of the pleura which closes off the space between them and prevents further fluid from accumulating. [3]
This is not to be confused with a lobectomy or segmentectomy, which only removes one part of the lung. There are two types of pneumonectomy: simple and extrapleural. A simple pneumonectomy removes just the lung. An extrapleural pneumonectomy also takes away part of the diaphragm, the parietal pleura, and the pericardium on that side. [1]
Solitary fibrous tumor (SFT), also known as fibrous tumor of the pleura, is a rare mesenchymal tumor originating in the pleura [1] or at virtually any site in the soft tissue including the seminal vesicle. [2] Approximately 78% to 88% of SFT's are benign and 12% to 22% are malignant. [3]
Shen’s cancer had spread to the pleura — which covers the lungs, chest cavity along the ribs, the sac around the heart, the nerves that control the diaphragm, the trachea, the windpipe, the ...
Pleural tumors may be benign (i.e. solitary fibrous tumor) or malignant in nature. Pleural mesothelioma is a type of malignant cancer associated with asbestos exposure. Under most other circumstances, pleural cancers are secondary malignancies associated with lung cancer due to its nearby location or as metastasis such as with breast cancer.
The pleural cavity, or pleural space (or sometimes intrapleural space), is the potential space between the pleurae of the pleural sac that surrounds each lung. A small amount of serous pleural fluid is maintained in the pleural cavity to enable lubrication between the membranes , and also to create a pressure gradient .
