Imaging findings
A small, mobile calcification is noted along the right pleural surface. This calcification was present in a different location on a previous scan and was not identified in its current location on an older scan, demonstrating its mobility within the pleural space.
Key takeaways
A pleuralith, also known as a pleural mouse, is a mobile calcified body within the pleural space. These are generally benign findings. Their mobility on sequential imaging is a key characteristic. The term 'pluralith' is preferred for its descriptive clarity.
