Case report

This is a case of a 32-year-old woman, G6P5, who was referred to our antenatal unit at 22 weeks of gestation for the ultrasound finding of omphalocele. Patient had non-contributive family or personal history. The first trimester scan was negative.
During our ultrasound examination, we saw the umbilical cord cyst measuring 34 mm x 35 mm. The initial view imitated an omphalocele. The urinary bladder was of normal appearance, with two umbilical arteries running along it's margin. Our diagnosis was an isolated umbilical cord cyst.
We performed an amniocentesis at 23 weeks of gestation with normal karyotype, 46 XX.
The follow-up ultrasound at 28 weeks showed the same findings.

The patient was hospitalized at 31 weeks of gestation for toxemia and delivered at 32 weeks via cesarean section. Our diagnosis of umbilical cord cyst was confirmed postnatally.
