This line stands out against the adjacent, uniformly dense lung fields caused by extensive calcifications. [2] Computed Tomography (CT): CT scans provide a more detailed view, revealing a clear demarcation between the calcified lung parenchyma and the spared subpleural area. The black pleura sign is evident as a peripheral lucent rim beneath ...
The endometrial tissue settles in the lung parenchyma or pleura. [8] A review of autopsy data showed that patients with endometriosis have bilateral pulmonary lesions, which supports the vascular embolisation theory. The pleural and/or diaphragmatic lesions were always found on the left side, which supports the theory of coelomic metaplasia.
Fluid in space between the lung and the chest wall is termed a pleural effusion. There needs to be at least 75 mL of pleural fluid in order to blunt the costophrenic angle on the lateral chest radiograph and 200 mL of pleural fluid in order to blunt the costophrenic angle on the posteroanterior chest radiograph. On a lateral decubitus, amounts ...
This impedes the centripetal drainage of the flow of lymph from the edges of the lung parenchyma and pleural surfaces. This causes the chyle to ooze extensively into the pleural cavity, leading to a chylothorax. In the case of yellow nail syndrome, or lymphedema, chylothorax is caused by hypoplasia or dilation of the lymph vessels.
Parenchymal hamartoma of the lung. The surrounding lung falls away from the well-circumscribed mass, a typical feature of these lesions. The hamartoma shows a variegated yellow and white appearance, which corresponds respectively to fat and cartilage. About 5–8% of all solitary lung nodules and about 75% of all benign lung tumors, are ...
Video-assisted thoracoscopic lung biopsy is the most definitive technique, but transbronchial biopsy has a yield of over 50% and can also be effective. [ 82 ] [ 83 ] The safety of the latter procedure in patients with diffuse cystic disease and the profusion of cystic change that predicts an informative biopsy are incompletely understood, however.
A hemothorax (derived from hemo-[blood] + thorax [chest], plural hemothoraces) is an accumulation of blood within the pleural cavity.The symptoms of a hemothorax may include chest pain and difficulty breathing, while the clinical signs may include reduced breath sounds on the affected side and a rapid heart rate.
Figure B shows lungs with asbestos-related diseases, including pleural plaque, lung cancer, asbestosis, plaque on the diaphragm, and mesothelioma. Extensive fibrosis of pleura and lung parenchyma The arrow points to an uncoated segment of asbestos fiber in this ferruginous body.
