There may be skin tags on the crotch, forming a tail

Skin abnormalities in the lumbosacral region are a clinical manifestation of tethered cord syndrome. Individual children may have skin tags on the crotch, forming a tail. 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.
