A bony outgrowth/exostosis measuring approximately 2.1 x 1.3 cm is seen along the outer aspect of the anterior right fifth rib, close to the costochondral junction. A well-defined soft tissue component (hypodense to the muscles), measuring approximately 3.7 x 3.7 cm showing no significant enhancement, is seen in relation to this bony exostosis. No underlying rib destruction is noted. Visualized lung fields are clear.
