Clinical Presentation (Pigeon Brest)

Figure peex_17a_n.jpg and peex_17b_n.jpg: Frontal and side view of a 13.1-year-old boy. The sternum and the adjacent parts of the chest wall protrude symmetrically on both sides; notice the transverse groove below, which is often occurring simultaneously. In a close side view the pathognomonic sternal protrusion and its site is recognizable at best; the protrusion may occur rarely in the upper third of the sternum (cranial type of pigeon breast).
