Skull Fracture?

Well the same day Brielle started preschool Dawson had a little fall and when I say little I mean little. He only fell like a foot but it was straight down on the concrete. Obvious by looking at the pictures it was bad and I was freaking out. I immediately called his neurosurgeons (who I have on speed dial) they told me not to worry and unless he was throwing up again he was probably okay. I was not satisfied with that because I do not think the understood the magnitude of this goose egg! Sooo we dropped Brielle off at preschool and headed straight to the pediatricians. I had no appt. and they do not take walk ins but I was not taking no for an answer and as soon as the pediatrician heard Dawson Milius we were seen immediately.
His pediatrician says don't worry I see these bumps all the time and I am thinking but how many of them just had a brain tumor removed? Then he says, "Well where do you want to do a CT Scan?" He also said if the lump was hard he would send us home but because it is gushy it could be a brain bleed! He said if it is a fracture they will take you by ambulance to Primary Children's hospital for observation. Might as well of told me he had a tumor again, I lost it!
Of we went to the hospital did a CT scan and there was no fracture! Though the doctor who read the scan was concerned about the amount of fluid he still had in his brain and told us to contact our neurosurgeons immediately! Again, freak out city! (One of the side effects of having your brain produce to much fluid is that it does not always know how to stop producing, so a permanent shunt would be the only solution) He said they might have to put in a drain and drain the excess fluid. Apparently the is 7mm of extra fluid still surrounding his brain.
I talked to the neurosurgeons they compared the scan to the last one they did and said though his fluids were high they were lower than his last appointment. The local hospital just does not deal with post op brain scans very often. awwww! Considering he was at like 21mm of extra fluid I took this as a good sign, healing!
After 3 hours of the unknown we were home and completely exhausted!

Tell me have you ever seen a bump that big???? The last two pics are the next day, the swelling was down a lot!
