pleural plaques are the most common manifestation of asbestos related disease and can be identified with a very high degree of specificity with CT.
Pathology
Fibres are thought to reach the pleural space via the lymphatic system. Macroscopically pleural plaques appear as grey-white regions of pleural thickening, often thickest at the margins, giving rise to the holly leaf appearance (aside from the colour of course).
Microscopically, they are composed of dense hyalinised collagen and are relatively acellular. The collagen is usually arranged in a loose 'basket-weave' pattern. Although asbestos fibres are sometimes seen, asbestos bodies are not a feature .
What does plaque mean
what is pleural thickening
pleural rub
pleural membrane
Pleural cavity is the potential space. There is no gap between the outer and the inner pleura. There is very little fluid in the pleural cavity. You have negative pressure in the pleural cavity.
The lungs
The pleural cavity is located in between the visceral and parietal of the lungs.
The thin watery fluid that occurs between the pleural membranes is called pleural fluid. This fluid helps to reduce friction between the two layers of the pleura, allowing smooth movement of the lungs during breathing.
Pyothorax is an accumulation of pus in the pleural cavity. Hemothorax is an accumulation of blood in the pleural cavity.
clinical importance of pleural recess
Pleural Mesothelioma is treatable, but not considered to be curable.
The potential space between the pleural membranes is called the thoracic cavity. This is also known as the pleural cavity in some instances.
