Case contributed by Dr Imran Ahmad Khan

Routine fetal anatomic scan at 20 weeks.

Patient Data

Age: 20 weeks' gestation

Fusiform dilatation of a 14 mm long segment of intra-abdominal umbilical vein. Diameter is approximately 8 mm. It mimics an intra-abdominal cystic lesion but fills up with color on Doppler examination.

Case Discussion

Fetal umbilical vein aneurysm (also termed as umbilical vein varix) is an uncommon anomaly that accounts for approximately 4% of the umbilical cord abnormalities. 

It is often associated with other congenital anomalies including cardiac anomalies and Down syndrome. Once this anomaly has been identified, a careful search for other fetal anomalies must be carried out. Amniocentesis could be offered to the patient.
