on a ct scan of the head it showed that one side of my sinus cavity didnt grow-but was solid bone instead. my father just had a ct scan and it showed the same thing. i have several siblings and half siblings-all biologically from my father and they all have abnormal bone growth in different areas too. heres what we know so far: me (27) and dad (62)- extra bone in sinus cavity me and full brother(25)- extra bone in skull me and half sister (36)- one leg longer than other ( 1") half brother (15)and half sister (36)- extra bone at base of spine half brother (15) and full brother 25)-scoliosis seems that each abnormality runs in different pairs of us. theres 7 kids and 4 have symptoms that made us discover this. the others havent had reason to check. ive read that agent orange did stuff with bones but is severe-ours is mild. what could cause this trait and mostly -what could make it affect each kid in a DIFFERENT AREA of the body?
