First-trimester umbilical cord cysts are often benign and resolve spontaneously. Early ultrasound detection is key for accurate obstetric management and reassurance.

Area of Science:

  • Maternal-Fetal Medicine
  • Diagnostic Ultrasound
  • Embryology

Background:

  • Umbilical cord cysts are typically diagnosed in the second and third trimesters.
  • Previous associations with fetal anomalies exist.
  • Early detection via ultrasound is possible.

Purpose of the Study:

  • To report the detection and characteristics of umbilical cord cysts in the first trimester.
  • To assess the significance and natural history of these early findings.

Main Methods:

  • Eight cases of cystic umbilical cord masses detected via endovaginal ultrasound at 8-9 weeks menstrual age.
  • Follow-up imaging and physical examination of neonates.

Main Results:

  • Cysts were eccentric, extraembryonic, and ranged from 2.0-7.5 mm (mean 5.2 mm).

Related Experiment Videos

  • Seven of eight cysts resolved by 12 weeks menstrual age.
  • Five infants followed to term had normal physical examinations and umbilical cords.

    • Conclusions:

    • First-trimester umbilical cord cysts are frequently identified using high-resolution ultrasound.
    • Most resolve spontaneously and appear to have no adverse impact on fetal development or neonatal outcome.
    • Early detection aids in appropriate obstetric management and parental reassurance.
