CTICasesThoracolithiasis
Imaging findings
Calcium scoring and follow-up chest CTs demonstrate a small, well-circumscribed, calcified mobile pleural nodule (containing a fatty core/marrow) in the right hemithorax. The nodule shifted position between scans.
Key takeaways
Thoracolithiasis refers to the presence of one or more free-floating calcified bodies in the pleural space. They are typically benign, asymptomatic, and thought to arise from costal cartilage fragments or fat necrosis.
