ruzuzu commented on the word foramen
"A somewhat rare congenital condition of the sternum is a sternal foramen, a single round hole in the breastbone that is present from birth and usually is off-centered to the right or left, commonly forming in the 2nd, 3rd, and 4th segments of the breastbone body. Congenital sternal foramens can often be mistaken for bullet holes."
