central sleep apnea and "brain tonsil"

[mbcdaj]

My grandson will face surgery for what is described as an area below the brain that is "like a tonsil" and has no particular use".  This tonsil-like area is growing "into a funnel" near the spine and is causing headaches and central sleep apnea.  He is a very bright young man, absolutely full of himself.  The neurosurgeon will "snip off" the area that is growing into the "funnel".  

I don't understand and was wondering if anyone is familiar with this condition and this type of surgery.  I'd appreciate any information you can give to me.

Your grandson is fortunate to have a grandparent who cares about him so much!

Could your grandson's physician be referring to a Chiari malformation?
