Understanding Caudal Dysplasia Sequence: Three Case Reports

Abstract

AbstractCaudal dysplasia or caudal regression sequence is a congenital malformation that is characterized by maldevelopment of the lower half of the body with variable involvement of the gastrointestinal, genitourinary, skeletal, and nervous system. Most cases are sporadic and associated with the presence of a single umbilical artery. We report three cases with varying morphological spectrum of caudal dysplasia diagnosed during the first trimester ultrasound.
