Umbilical catheters (UC) are ubiquitously utilized in neonatal intensive care units (NICU) during the early neonatal stage. Traditionally, these catheters are placed blindly, with the external length of the catheter being used to approximate catheter depth. This then requires subsequent radiographs to be obtained to assess for position, often in a sterile field, with considerable dead time. This exhibit will educate the viewer about the use of ultrasound guidance in the placement of these catheters. Read More

This educational exhibit provides an overview of the embryologic development and postnatal anatomy of the umbilical region, emphasizing its sonographic evaluation and the clinical relevance of congenital remnants in pediatric patients. Understanding how transient fetal structures transform into definitive postnatal ligaments and potential remnants is essential for accurate diagnosis and differentiation of midline abdominal pathologies.
A diagram-based embryologic summary will clarify the relationships among the umbilicus, allantois, and vitelline (omphalomesenteric) duct—structures often confused in imaging. Step-by-step visuals illustrate how the allantois forms the urachus, which fibroses into the median umbilical ligament; how the umbilical arteries and vein become the medial umbilical ligaments and ligamentum teres hepatis; and how the vitelline duct contributes to the omphalomesenteric duct and portal venous system. Incomplete regression may result in Meckel’s diverticulum or urachal anomalies.
High-frequency ultrasound of the umbilical and prevesical (Retzius) space will be presented, depicting the normal relationships of the bladder dome, medial umbilical ligaments, and urachal remnant. A summary diagram will link each embryologic structure with its potential anomaly if regression fails. Representative sonographic and schematic images will highlight characteristic appearances and practical scanning tips for accurate evaluation.
Two illustrative pediatric cases demonstrate how these remnants may mimic surgical emergencies: an infected urachal cyst presenting as right-lower-quadrant pain, and a Meckel’s diverticulum acting as a lead point in ileoileal intussusception. Recognition of their embryologic origin and ultrasound appearance prevents misdiagnosis and guides appropriate management. Read More
