I just recently ran across a Chiari Malformation (syrinx)/scoli post.

No, I don't have ACM. I "simply" have unexplained communicating hydrocephalus (with an original 28 year old non-revised VP shunt - manifesting at age 10).

The two (hydro and scoli) have been partners before (i.e., neural tube defects - particularly SB - and X-linked).

I'm very curious about the connection here - under any circumstance ...
