Thoracolithiasis – CT findings of intrapleural loose bodies

Thoracoliths are rare benign intrapleural loose bodies, often containing calcification, that are mobile in the pleural cavity. The presence of these intrapleural nodules is referred to as thoracolithiasis. The exact etiology of thoracoliths is unknown, but they presumably result from a prior episode of mediastinal (epipericardial) fat necrosis. Thoracoliths are usually asymptomatic and incidentally encountered on CT.However, they sometimes pose diagnostic challenges, as a thoracolith may be located within a pleural fissure, and is then indistinguishable from a pulmonary nodule.
