Antenatal diagnosis of fetal umbilical hernia on mid-trimester sonography

Congenital hernia of the umbilical cord (CHUC) is a rare and often under-recognized anterior abdominal wall defect that is frequently misdiagnosed as an omphalocele. It represents a distinct embryological entity with a benign course and favorable prognosis. Prenatal ultrasonography is crucial for accurate diagnosis, appropriate parental counseling, and safe perinatal management, particularly to prevent bowel injury during umbilical cord clamping. We report a case of isolated fetal umbilical hernia detected on a routine mid-trimester anomaly scan and highlight key sonographic features that aid differentiation from other abdominal wall defects.
