Sorry I have posted on this before but I am desperate for someone to reassure me. Ds is 8 and for the last 5 years we have noticed a bony lump on top of his head. First GP we saw about this 5 years ago said exactly in the middle of his head where fontella closed up uneven. It bothers me from time to time so mentioned to a paediatrician who has referred us for a MRI scan. Has anyone's else child got this bumpy type of head. I am sick with worry and don't know how I am going to wait another 6 weeks . I have googled (stupid I know) and it sounds like a sagital ridge but I don't think this can happen at his age. Other possibilities are scaring the life out of me. Anyone able to help calm me down.
