These types of abnormalities arise from specific structures formed in the caudal mass, for example if proper differentiation of the caudal mass doesn't occur, it could result in a type of spinal dysraphism.

Patients suffering from caudal regression syndrome can experience a varying degree of the abnormality ranging from partial lack of the tail bone and pelvis to more significant cases where there may be paralysis and, as a result, inhibited function in the bowel and bladder. This abnormality can be caused by the caudal cell mass not developing properly
