TermDescription
Caudal AgenesisThis term is used synonymously with sacral agenesis, since in most cases only the sacrum is involved. It is a loosely defined syndrome of vertebral malformations, ranging in severity from agenesis of the coccyx to absence of the sacral, lumbar, and even lower thoracic vertebrae. With high sacral and above malformations, there may be significant neurological deficits, as well as anomalies involving the genitourinary tract, intestines, and the respiratory system.
