Caudal regression syndrome from radiology and clinical perspective: A case series and a proposed new integrated diagnostic algorithm

Caudal regression syndrome (CRS) is a rare inherited disorder associated with orthopedic deformities, as well as urological, anorectal, and spine malformations. We present 3 cases of CRS found in our hospital, along with the respective radiologic and clinical findings of the disease. With different problems and chief complaints from each case, we propose a diagnostic algorithm that can be used as a helpful tool in managing CRS. CRS is a complex and rare congenital disorder that affects multiple systems and can result in a range of malformations. The diagnostic algorithm proposed from our findings from 3 CRS cases is important to help healthcare providers identify the types of CRS and apply a more individualized approach to improve the quality of life for the patient.
