Hi can any1 help me,my 8 year old son has optic nerve hypoplasia(undeveloped nerve frm brain 2 eye) he is blind in 1 eye.he has loads nose bleeds,headaches,body cramps,stomach pains & stiffness causing him pain & discomfort any time of day especially on left side of body & his neck,plus toiletting problems. So an mri of brain was done and ultra sound of bladder & kidneys,we haven't yet received the written report of US but radiologist said his bladder was thickened which shows he can only hold 5 table spoons of fluid but should be able to hold 25-30 tbl spoons before feeling the urge @ his age,& even after he goes toilet several times his bladder still does not empty (WHAT DOES THIS MEAN ?)... Now the mri results of brain & orbits:- under developed optic nerve & high signal in T2. Elsewhere there are bilateral high signal small scattered foci in both hemispheres in periventricular regions which are non specific and of uncertain significance to patients age.( CAN SOME ONE PLEASE HELP ME UNDERSTAND)
