Allantoic cyst of the umbilical cord detected in the first trimester with good pregnancy outcome

Abstract Allantoic cysts of the umbilical cord are embryological remnants of either the allantois or the omphalomesenteric duct. These cysts represent a rare ultrasound finding especially in the first trimester. Allantoic cysts can be associated with fetal malformations and chromosomal aberrations or are characterised by spontaneous resolution and good pregnancy outcome. Here we present a rare case of umbilical cord cyst detected by ultrasound in the first trimester with later resolution and favourable pregnancy outcome.

Umbilical Cord Cyst

Umbilical cord cyst refers to any cystic lesion that are associated with the umbilical cord. They are classified as true cysts or pseudocysts. True cysts are small remnants of the allantois, whereas false cysts originate from liquefaction of Wharton Jelly. In present case, cyst was diagnosed at birth without any associated congenital anomalies and resolved spontaneously within a few days requiring nil surgical intervention. Umbilical cord cysts deserve special attention since 20% of them, regardless of type, are associated with structural or chromosomal anomalies. Because of this, fetal karyotyping and amniocentesis should be considered when cysts persist beyond the first trimester.

Increased Nuchal Translucency

Monozygotic twins with discordant karyotypes for trisomy 13 are rare. We report a case of a spontaneously conceived pregnancy who presented with first-trimester ultrasound finding of umbilical cord cyst and increased nuchal translucency in Twin A and no abnormalities in Twin B. Amniocentesis revealed 47,XY,+13 karyotype in Twin A and 46,XY karyotype in Twin B. Selective fetal reduction was performed for Twin A. Twin B was delivered at 32 weeks gestation with normal phenotype. Peripheral blood karyotype revealed 15% mosaicism for trisomy 13 and skin fibroblast revealed 46,XY karyotype. The surviving twin will be monitored for potential complication of uniparental disomy 13 and mosaic trisomy 13. This case reinforces the need for early ultrasound and nuchal translucency measurements, especially in twin gestations.

Heterotopic pregnancy is a rare clinical condition where both intrauterine (IU) and extra uterine pregnancy coexists. In a non-ART set up diagnosis of tubal ectopic pregnancy becomes challenging and difficult with coexisting intrauterine viable pregnancy, even when presents with ruptured form. Author is presenting one of his challenging experience in managing successfully such type of heterotopic ruptured tubal pregnancy in first trimester where extra uterine ruptured tubal pregnancy was addressed by laparoscopic salpingectomy under spinal anaesthesia with minimal uterine manipulation to continue intrauterine pregnancy till term and thus had a successful pregnancy outcome.

Vestiges of the omphalomesenteric or vitello-intestinal duct and the pathologic implications attributed to these remnants have been treated in great detail by several investigators. Persistence of the omphalomesenteric duct is associated with such conditions as Meckel's diverticulum, umbilical fistula, mucosal polyps, and sinuses or cysts of the umbilicus. Remnants of the duct in the umbilical cord, although infrequent, are located outside of the triangle formed by the two umbilical arteries and the umbilical vein, are usually discontinuous and are often represented by a small lumen lined by cuboidal or columnar epithelium. This study will examine the ultrastructure of these cells.
