Chiari-like malformation question

In relation to SM, have there been studies on the percentage of dogs that eventually develop syrinxes in later life, that have a "mild chiari-like malformation", as opposed to severe CM?

I know that they are now saying that up to 90% of Cavaliers probably have some form of CM, but are alot of dogs diagnosed SM that have just a very mild malformation? :confused:
 
This is information that is hoped to eventually come perhaps from neurologist Geoff Skerritt in the UK as he has MRI'd over 600 cavaliers, many repeat MRIs too.

A lot of dogs with mild malformation have severe SM and vice versa -- there doesn't seem to be any direct correlation although a severe malformation would almost certainly put extra pressure on a dog's hindbrain.

Leo has a mild malformation and had a small syrinx when MRId almost 4 years ago. The malformation won't get any worse presumably, but the syrinx often does.

The main correlation to pain and symptoms is the width of the syrinx.
 
Spencer has a moderate-severe malformation but no syrnixes. He also has some hydrocephalus. He has been MRI'd twice, January 2007 and June 2008.
