    ABSTRACT: The purpose of this study was to report the outcomes of fetuses with the finding of an umbilical cord cyst during nuchal translucency examination in a low-risk population. A retrospective study was conducted in a large tertiary referral academic center over a 3-year period. All fetuses with umbilical cord cysts during the nuchal translucency scan were recruited, and their medical data concerning the pregnancy and neonatal course were analyzed. Eight fetuses (0.7%) had a diagnosis of an umbilical cord cyst among the 1080 nuchal translucency examinations. The mean cyst diameter was 19 mm (range, 10-38 mm). The male to female ratio was 6:2. Isolated umbilical cord cysts were found in 5 cases (62.5%), and in all, the nuchal translucency measured less than 2 mm; the cysts resolved; and the outcomes were normal. Three fetuses (37.5%) had additional associated malformations. In all of them, the cysts persisted during pregnancy. Two of them had increased nuchal translucency (3.2 and 4.2 mm). In these 2 cases, 1 fetus had a hypoplastic left heart with a normal karyotype, and the other had multiple malformations and trisomy18. Both pregnancies were terminated. The third case, with normal nuchal translucency, had an ectopic kidney and a patent urachus, which closed spontaneously at 23 weeks and resulted in a normal pregnancy outcome. A favorable outcome is expected when an umbilical cord cyst diagnosed during late first trimester presents as an isolated finding associated with normal nuchal translucency and resolves later on.
