Dermal sinus

Patients with spinal cord tethering syndrome, especially children, should be alert to the clinical manifestations of the sinus or subcutaneous mass. Tethered cord syndrome (TCS) is a syndrome that causes a series of neurological dysfunction and deformity due to various congenital and acquired causes of the spinal cord or cone being stretched. Because the spinal cord is stretched in the lumbosacral spinal cord and causes abnormally low cones, it is also called the low spinal cord.
