 Another way to differentiate a healthy baby from a baby with Bochdalek Hernia, is to look at the chest immediately after birth.If the baby has a Bochdalek Hernia it may appear that one side of the chest cavity is larger than the other and or the abdomen seems to be scaphoid (caved in).Most likely, Bochdalek hernias are formed throughout the growth process and organ construction during fetal development.
