Pleural calcification

In the presence of organic blood clots or cheese necrosis in the pleural cavity, calcium salts can be deposited to form pleural calcification. Pleural calcification is more common in tuberculous pleurisy, purulent pleurisy, and post-traumatic hemothorax. Some pneumoconiosis, such as talc and asbestos, can also have pleural calcification, and are often bilateral. Pleural calcification is often accompanied by pleural thickening and adhesions.
