Hi this is Dr Hill. Please give me a moment to type my response. Thank you
Please post a picture of his face to give a better picture of what is going on. From what you are describing, there are two possibilities. One is that the bone is more prominent because the muscles on top of the head have atrophied and the other is that the muscles are normal, but the increase in size is due to a mass. Byron does need a physical exam to help determine which is the primary issue. Please ask any follow up questions. If you can post a photo, that would be very helpful. You can continue posting on this thread for a couple of days, even after rating my response.
