My son did not have CSF flow problems noted, he did have a 20 mm herniation which caused problems due to crowding. Whether that maybe meant that there were problems with flow or not, I'm not 100 % sure, but there were no notes about this being an issue.
Looking at the MRI you could see where the crowding was occurring. So, in my son's case, yes there were chiari symptoms without flow blockage from what I understand. He did not have TC or syrinx.
Hang in there....you will find the answers you need. Not all drs think that it is a problem even at lower levels. My son's was very large and for a long time he did not have significant symptoms, so the reverse is often true, from what I have read.

All I can ask is this a chiari specialist?.....to be considered for surgery, besides having symptoms....a blockage of CSF and over crowding are looked at than quality of life......
There r chiari drs that believe in Chiari 0 which is a herniation less than 5 mm........I was told and I may have mentioned this is ur last thread but I was told my chiari after surgery is still at 2 mm and to expect to have chiari symptoms......
I do still have a blockage of CSF, but from a bulging disk......so to answer, can he have symptoms without a blockage...MHO is yes.....are they all chiari...possibly not...chiari related...more likely.....
