A fibrin clot in the pleural cavity (“fibrin body”, “fibrin ball”, or “pleural mouse”) can be formed in the resolution process of exudative effusion or hemothorax – a soft tissue globule up to 2 cm in diameter. On CT this globule contacts the pleural surface and can spontaneously shift after a change of the patient’s position or at a repeat imaging. The fibrin body can exist for a long time, resolve, or calcify turning into a thoracolith (↑).
