A Rare Case Report: Caudal Regression Syndrome in the Baby of a Mother with Hypothyroidism

Caudal regression syndrome (CRS) is part of a spectrum of conditions that include imperforate anus, sacral agenesis and syringomyelia. Most cases of caudal regression are sporadic or associated with gestational diabetes. In this case study, we describe a case of characteristic CRS in a patient of a mother with hypothyroidism with anal atresia, flexion contracture on the hips and knees, pes equinovarus, and the absence of a sacrum and coccyx.
