Hello All,
I came across this board while researching my illness. I have syringomyelia from T2 to T12 5mm in width and in the cervical spine. Mine is not related to Chiari.
BTW, Syringomyelia is a progressive and terminal condition if not treated. It is very important to see a Neurologist and to seek treatment. Some people may have a stable condition. (one that does not progress) However, that does not mean it doesn't cause death. A minor car accident can immediately make the condition worsen. Pneumonia, a severe cough, excessive weight strain and other strains can make the syrinx larger. The syrinx can grow on its own.
Saying Syringomyelia is not terminal is incorrect. If left untreated it can be terminal. Even with treatment, some excessive damage, can be permanent. If it grows to your cervical spine, and causes nerve issues with respiration, it is very terminal.
