What does this mean?

well we just got my 5 year olds MRI of the spine results its still 17mm but now they are saying its severe chiari with kinked cervical cord and fulid in the cervical portion of the cord and the cord is floded in the chari area im not 100% on what this all means but the NS here said we need surgery we are going to denver to see another NS to see what they say we are praying for the best

Because she said if it was not so bad she would monitor it but after the last MRI she felt better not to wait time and have me see a pediatric NS
