Hi S., my son is 14 and has an inverted sternum. Because of this and other symptoms (long fingers and arms, joint flexibility, etc.) he was eventually given an echocardiogram and found to have an enlarged aorta, which THEN led to a diagnosis of Marfan's Syndrome. His inverted sternum is not causing him breathing problems, but he was having really bad chest pains which doctors attributed not to the sternum but to costonchondritis (inflammation of the joints in his ribs). I don't know if that was because of the Marfan's or not. Anyway, my son's pectus excavatum (that's when it goes inward, right?) is not severe enough for doctors to have advised surgery, so I'm sorry I can't help with any advice there. I just wonder if your daughter has already had an echocardiogram to check for Marfan's since that (inverted sternum) is a characteristic of Marfan's. Let me know what happens at the doctor's. I'm curious. Good luck, too :) L.
