Hello,
Poor guy, that is terrible he has had to go through all of this already, at such a young age.
You are positive he is male but not female? It is late here so I will look at the x-rays again tomorrow
but did but it almost looks like the visible outlines of possible eggs. If not, then it is something else,
they mentioned fluid or something else. The calcium is a little high which can occur with some tumors
but most of the time it indicates egg production.
The Uric acid & AST look to be in range.
Has he lost any weight recently or been maintaining?
Continue with daily fluids right now. He is not on any medications right now, correct?
If you can afford it, you could consider an ultrasound to see if they can try to pinpoint anything else.
I'll write more on Monday when I get a chance.
