A case of umbilical cord cyst was identified via 2-dimensional and 3-dimensional sonographic examination at 8 weeks' menstrual age. The cyst was solitary, measuring 18.0 mm, and it was located close to the placental insertion on the umbilical cord. The gestational sac and yolk sac diameters and the fetal heart rate were within normal ranges for menstrual age. Follow-up 3-Dimensional sonographic examination in the second trimester showed complete resolution of the cyst. Amniocentesis revealed a normal karyotype, and a normal infant was delivered at term.
