Umbilical cord cyst presenting as an omphalocele at 15 weeks' gestation. A case report.
A small, cystic structure was identified on a routine ultrasound scan performed for dating at 15 weeks' gestation. Originally it was thought to be an omphalocele, but further examination confirmed its origin in the cord several centimeters distal to the fetus. Close scrutiny of ultrasonograms is important since technical capabilities permit high-resolution scans during early gestation.
