Congenital

This radiograph demonstrates bilateral cervical ribs, right greater than left. They are congenital and may be of no clinical significance. In some individuals, it can cause or contribute to thoracic outlet syndrome by compressing the subclavian vein, artery, and/or nerve. Cervical ribs may be resected in these cases.

There is also an incidental small, dense (likely calcified) nodule in the right lower lung and a probable calcified right hilar lymph node. This patient lives in an endemic area for Histoplasma capsulatum. Remote infection is the most likely etiology.
