Giant Cystic Umbilical Cord in a Post-Term Nigerian Neonate

Abstract

Background/Aims: Umbilical cord cysts may be described as true cysts or pseudocysts. True cysts have an epithelial lining and are remnants of the allantoin while pseudocysts arise from liquefaction of Wharton’s jelly. Umbilical cysts complicate as many as 3% of pregnancies but generally regress by the end of the 1st trimester. Cysts that persist beyond 12 weeks may be associated with other malformations.Giant umbilical cord pseudocysts are extremely rare malformations.

Methods: Reports from the records of a one-day old male referred to ournewborn unit were reviewed. Details of his treatment, progress and ultimate discharge were documented.

Results/Case Report: A one-day old male delivered via emergency caesarean section on account of foetal distress was referred to our newborn unit on account of a large umbilical cord. GA at delivery was 43 weeks. Birth weight was 4kg. No anomalies were recorded on prenatal Ultrasound Scan. A large cystic swelling was noted extending for most of the length of the cord. Three umbilical vessels could be seen clearly through the swelling. Largest diameter was about 8cm. Systemic examination was essentially normal. Abominopelvic ultrasound scan showed normal findings.

Conclusion: Giant cystic umbilical cords are rare and may be associated with chromosomal or other significant structural anomalies. In the absence of other anomalies, treatment is conservative as cyst regresses with time.
