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 parietal pleura is subdivided according to the surface it covers. The costal pleura is the pleural portion covering the inner surfaces of the rib cage, and is separated from the ribs/cartilages and intercostal muscles by the endothoracic fascia.
Pleurodesis is a medical procedure in which part of the pleural space is artificially obliterated. [1] It involves the adhesion of the visceral and the costal pleura. The mediastinal pleura is spared.
Relatively small tumors are designated T1, which are subdivided by size: tumors ≤ 1 centimeter (cm) across are T1a; 1–2 cm T1b; 2–3 cm T1c. Tumors up to 5 cm across, or those that have spread to the visceral pleura (tissue covering the lung) or main bronchi, are designated T2. T2a designates 3–4 cm tumors; T2b 4–5 cm tumors.
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]
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.
That pleural effusion, a collection of fluid in the chest, doesn’t normally occur with COVID-19, and more testing revealed that Shen had a large thymoma, a rare type of cancerous tumor starting ...
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 .
