Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone , but calcium can be deposited abnormally in soft tissue , [ 1 ] [ 2 ] causing it to harden.
This PA chest radiograph demonstrates an abnormal contour in the right hilar region, with visualization of the pulmonary vessels through the mass (the hilar overlay sign) indicating its posterior mediastinal location. On resection this was found to be a benign solitary fibrous tumor of the pleura.

Aortic unfolding is an abnormality visible on a chest X-ray, that shows widening of the mediastinum which may mimic the appearance of a thoracic aortic aneurysm.
