Traffic syringomyelia is actually a congenital syringomyelia, mainly due to the failure of the sphincter in the spermatic cord to close after birth, causing the fluid in the abdominal cavity to communicate with the fluid in the syringomyelia, which can be large or small with changes in abdominal pressure. If there are more orifices where the sphincter communicates with the peritoneal cavity, there is also the possibility of forming a congenital inguinal hernia. Therefore, traffic syringomyelia may often be accompanied by a hernia, and after repeated compression, the mass may shrink and may itself induce a hiatal hernia.
