Episternal ossicles
Episternal ossicles (or suprasternal ossicles) are small bones that are sometimes present at the upper end of the chest bone. The prevalence of these ossicles is around 1.5%.[1]
Structure
The episternal ossicles are oval-shaped bones that are occasionally found at the superior and posterior border of the manubrium. The episternal ossicles were first described by Cobb in 1937.[2] They may be present unilaterally or bilaterally.[3] Its size ranges from 2–15 mm depending on individuals.[4] These ossicles are asymptomatic and does not cause any harm, although it may be diagnosed as fracture, vascular ossification or calcified lymph nodes.
