pleural friction

The pleural friction is caused by pleural inflammation. The exuded fibrin deposits in the visceral and parietal pleura, which makes the surface of the pleura rough. When the breathing, the two layers of pleura rub against each other, and the feeling of rubbing like leather can be felt when palpating. The signs are most clear on the affected side of the midline and the lower part of the sac. When pleural effusion occurs, the two layers of pleura are separated and the pleural friction is lost. The feeling of friction can reappear during the absorption of the effluent.
