My 7-yr-old grandson has what appears to be a quarter-size lump in his skull formation on the top left corner of his forehead. His pediatrician says it is probably normal. (a misshapen skull is normal?). My grandson will be seen soon and referred to a specialist. He had grade-4 brain bleed when he was two days old and thankfully has recovered 100% and is above average intelligence. It is not a fatty deposit on his bone that moves around, it is his bone protruding in a perfect circle. Thank you for your response.
